description:
compiler.mk: Fix Ada packages when PKGSRC_COMPILER=clang

Only one compiler is used when "ada" is listed in LANGUAGES, and that
is the one built by the lang/gcc-aux source package.  When PKGSRC_COMPILER
is defined as anything else other than "gcc", the Ada packages fail to
build.  This can be seen when clang is used with CLANGBASE=${LOCALBASE}.

This straight-forward fix is to override the user specification of
PKGSRC_COMPILER when Ada is specified and define it as "gcc" in all cases.
Tested on NetBSD 6.1 amd64 with CLANGBASE=${LOCALBASE}
