Patched configure
Disable visibility on Darwin, fixes build.
Add support for Darwin.  Patch from nixpkgs.
Remove GNU ld options on Darwin too.
Remove -soname and avoid stripping on Darwin.  Fixes build.
The syntax of the Configure architecture table changed recently. Our
entries for NetbSD architectures without assembler routines and Interix
containing ::::::... need to be updated, else -fPIC ends up in the
object-to-build list of crypto/modes. The correct entry snippet is
stored in ${no_asm}.
make test has run successfully in pkgsrc-current and -2013Q3 on
Shark (arm, asm-less) as well as i386 (with asm routines).
update x11-links to 0.80:
- update to handle Xcomposite removal
