#66888: graphene @1.10.8_0+universal: arm64/x86_64 fails due to conflicting
pkgconfig files

--------------------+----------------------
 when building graphene for arm64 and x86_64 universally, the two builds
 are quite different and the pkgconfig files don't match.

 The arm64 arch builds with neon active, and the x86_64 arch builds with
 SSE2 and a number of enabling flags.

 unfortunately pkgconfig still has no "-target" option or "-arch" option to
 control the returned flags. According to the current muniversal PortGroup
 functionality, we are expected to find a way to merge these meaningfully.

 For the CFLAGS, it's easy. Clang will just ignore the flags that don't
 apply to the arch it is building for, so sending SSE2 flags into an
 arm64/neon build is no problem. So that part is easy enough to unify.

 Then maybe we can get away with this? :
 {{{
 graphene_has_sse2=1
 graphene_has_neon=1
 ...
 }}}

 I wonder what any software would use those pkgconfig items for anyway (if
 they can even query them...)
