Yes, the compiler is part of the build environment.  However, the
_runtime_ environment can, and often is, composed of parts created
under different _build_ environments.  When all the parts adhere to
the same ABI, this works wonderfully.

POSIX standardises a few common compiler flags (-I, -L, etc.), and
pretty much all relevant compilers support these.

You are proposing to _intentionally_ break compatibility between
compilers where no issue would exist absent pkg-config.  I find that
counter-productive, if not outright rude.
