This is probably pretty easy, you just do it the same as the
FOO_LIBS/FOO_CFLAGS stuff done now. I would call the subst'd variable
FOO_REQUIRES or something.
You'll also have to have AC_SUBST(FOO_REQUIRES) in configure.in as you
do now for the LIBS/CFLAGS.
Anyway, if you look at the m4 file I bet you can make this change in 10
minutes, the only complicated part looks like how to remove the version
number checks in shell code. A robust solution to that might be for
pkg-config itself to have an --output-requires option or something.
