Fix path splitting in get_compiler_dirs() with GCC/clang on Windows

It was using ':' as a path separator while GCC uses ';' resulting in bogus
paths being returned. Instead assume that the compiler uses the platform native
separator.

The previous splitting code still worked sometimes because splitting
"C:/foo;C:/bar" resulted in the last part "/bar" being valid if "<DriveOfCWD>:/bar"
existed.

The fix also exposes a clang Windows bug where it uses the wrong separator:
https://reviews.llvm.org/D61121 . Use a regex to fix those first.

This resulted in linker errors when statically linking against a library which
had an external dependency linking against system libs.

Fixes #5386
