Re: Add Mach-O support to check-shlibs

[Jonathan Perkin <jperkin%joyent.com@localhost>]

I've made a few more fixes to this work:

  https://github.com/jsonn/pkgsrc/compare/trunk...joyent:joyent/review/check-macho

The main one is updating _CHECK_SHLIBS_ERE to now check all .dylib and
.sl files to match the .so handling.  Previous to this sqlite3-tcl was
letting through broken DSOs in sub-directories, but now correctly
fails with:

  $ bmake _check-shlibs
  => Checking for missing run-time search paths in sqlite3-tcl-3.8.11
  ERROR: lib/sqlite3/libsqlite3.8.11.dylib: missing library: libsqlite3.8.11.dylib
  *** Error code 1

Unless there are any objections I'll commit this in the next couple of
days.

Thanks,
