* Make cc_toolchain_utils.bzl more reusable
By using getattr, the helper functions in this file can be reused in
rules that do not define all of the framework attributes, e.g. bootstrap
rules.
* Bootstrap make reproducibly on Linux and macOS
Uses the Bazel C/C++ toolchain to bootstrap make and ensure that the
resulting binary contains no absolute and thus non-hermetic paths.
Building make reproducibly helps with remote caching and removes the
dependency on a C compiler installed on the host.
* Adds toolchain for freebsd.
* Address buildifier lint warnings.
* Use /usr/bin/env bash
* Leave the Linux-specific shebang alone.
* Adds note about Bazel CI issue requesting for FreeBSD support and experimental status.
* Fix typo.
* Clean up trailing whitespace.
* Updates bazel-skylib version for tests to pass on FreeBSD.
* Update foreign_cc/repositories.bzl

* Pass toolchain and user env variables to make invocation
* Rename configure --> make
* Add integration test coverage for make flag passing
This requires making the make_simple Makefile more realistic by
* using CXX and forwarding it to the wrapper;
* using CXXFLAGS instead of CXX_FLAGS and not overwriting its contents.
Certain (C)Make projects (such as [AFL++](https://github.com/AFLplusplus/AFLplusplus)) emit binaries that are symlinks to other emitted binaries. When built with `rules_foreign_cc`, this can lead to non-deterministic dangling symlink errors since Bazel visits the outputs in an unspecified order. This is fixed by resolving symlinks among the emitted binaries, just like it is already done for libraries.
Since 466c32c70f any changes you made
while testing rules_foreign_cc, or changes to those rules, would not
invalidate the CMakeCache.txt and lead to build issues. It wasn't the
case before that because new temp dirs were used each time.
* build OpenSSL using MSVC toolchain on Windows
* Display lib name in progress message
Before this commit, when building OpenSSL using MSVC, the progress
message would display "Building openssl_msvc_".
After this commit, the progess message would display
"Building openssl".
* Add test to verify linkage with OpenSSL libs
* Add test to verify linkage with Curl libs
Note that linker errors occur in applications that link with libssl
and libcrypto if libcrypto comes before libssl on the linker
command-line. Swapping the order of libcrypto and libssl in
BUILD.openssl.bazel resolved the issue.
The macros utilise bazel "transitions" to set the `make` toolchain used
in the configure_make(), cmake() or make() rules to
a given make variant toolchain, e.g. preinstalled_nmake.
Note that the msvc constraint was removed from the
`exec_compatible_with` attribute of `preinstalled_nmake_toolchain` as
the condition is not actually met even when building with msvc. See
https://github.com/bazelbuild/bazel/issues/7730.
This will be tested in PR#729
If a user specifies a PATH value as part of an `env` attribute, the
value will be prepended to the existing PATH.
An example requirement for this change is that the MSVC build of
OpenSSL requires that the Netwide Assembler (NASM) must be on the
PATH.
This change is required when using the MSVC toolchain on Windows,
as paths for tools such as the compiler contain whitespaces (e.g.
C:\Program Files\...)

* Convert MSVC flags by replacing slashes with dashes
This overcomes bugs in MSYS2 where leading slashes are converted to
paths, e.g. "/nologo" is converted to "C:\msys64\nologo".
This commit would modify the flag to become "-nologo". MSVC supports
both slashes and dashes for flags.
* Update foreign_cc/private/cc_toolchain_util.bzl

* Enable examples tests on windows
* Fixed windows absolute paths being treated as relative.
* Escape windows backslashes for sed replacement
* Improve `//cmake_hello_world_lib/static:libhello` example
* Refactor _env_prelude method to be public (589)
In an upcoming commit, the method will be used to set the PATH,
INCLUDE and LIB environment variables in Windows when building GNU
Make from source
* Build make from source on Windows (#589)
The built_tools_framework.bzl file was modified so that the PATH,
INCLUDE and LIB environment variables are set from the C++ toolchain,
e.g. MSVC.
The PATH environment variable is prepended with the path to the
toolchain's linker, otherwise the MSYS2 linker would be used instead
of MSVC (as they are both named link.exe).
* Fix tool_prefix for CMake.
Set the prefix before the first CMake invocation (where all the extra
flags are passed), and don't set the prefix for the `--build` and
`--install` invocations of CMake.
Fixes #685.
