description:
implement {NOT,ONLY}_FOR_COMPILER so that packages can be marked as
requiring a specific compiler (most often those which use gcc-specific
hacks^wfeatures).

this allows users to define PKGSRC_COMPILER to multiple real compilers in
order to implement a compiler preference. for example,
PKGSRC_COMPILER="sunpro gcc" will use sunpro as the default compiler,
and fall back to gcc where a package is marked NOT_FOR_COMPILER=sunpro
or ONLY_FOR_COMPILER=gcc.
