description:
Add a new option 'always-libgcc', whether to install libgcc.
If the pkgsrc compiler is GCC, don't install libgcc.

Having an older libgcc is problematic: it may be missing symbols from
newer libgcc. This is what happened in PR pkg/54506.

Use this on gcc-aux and gcc5-aux: the libgcc_s.so they install is going
to be older in all the operating systems these packages support.
(Other GCC packages will require a more elaborate rule)

Leaving SmartOS unchanged, by request from jperkin.
