[Autotools] Don't compare $CC, $CXX to exact compiler names
https://bugs.webkit.org/show_bug.cgi?id=119683
Reviewed by Gustavo Noronha Silva.
Instead of comparing $CC and $CXX to exact compiler names (like 'gcc', 'clang++' etc.),
use the compiler version checks to also specify the broader compiler collection of which
the used compiler is a member of. This avoids failures in some border-line cases where
the user would still use either a GCC or a Clang compiler but provide it through a symbolic
link that was specified via the CC/CXX environment variables.
* Source/autotools/CheckSystemAndBasicDependencies.m4: Store the detected C/C++ compiler collection
in c_compiler/cxx_compiler. Throw an error if no supported compiler was found.
* Source/autotools/SetupCompilerFlags.m4: Test for a specific compiler by checking against
c_compiler/cxx_compiler rather than CC/CXX values.
