The directory from where the source files are sought when producing a
coverage report in text or XML format should not be the build directory
but the source directory instead.
Object files from a custom_target are like external objects and must be
added to the project.
Object files from a generator are automatically used by MSBuild, since they
are part of the CustomBuildStep and thus part of the same project as the
current build target.
With the change to cc.links to translate unix link flags, this is no
longer needed and is wrong because it hasn't kept-up with the improved
default cc.find_library implementation.
Instead, return the values of the test and benchmark setup data files so
that the ninja/osx/vs backends can use those filenames instead of
hard-coding them.
When a CustomTarget is run with a command that is an executable built
by the project which also has a DLL built in the same project as a
dependency, the EXE can't run on Windows because the DLL can't be found.
On UNIX-like systems, we set the RPATH using the linker so these
dependencies can be found, but on Windows the only way is to set the
PATH environment variable.
The same problem exists for tests, so we reuse that infrastructure by
creating a new meson_exe.py script that can be used as a wrapper to run
CustomTarget commands on Windows. This can later also be extended to add
support for setting an environment while calling the command needed to
generate a CustomTarget: https://github.com/mesonbuild/meson/issues/266
Without any -O options, gcc does not generate properly debuggable code.

gcc recommends -Og, but that isn't supported by clang, so we use -O0
See https://github.com/mesonbuild/meson/pull/509 for more discussion
We now use .links() to detect if a C compiler function is available
or not, that way the user doesn't need to specify all the possible
includes for the check, which simplifies things considerably.
Also detect glibc stub functions that will never work and return
false for them.
