Update base/gcc to work with devel/freebsd-gcc6.

- Explicitly set all the toolchain <foo>_FOR_TARGET variables.
  GCC's default guess for CC, etc. happened to work with the
  powerpc64-gcc port, but fails when the binaries have a suffix
  like the '6' suffix in freebsd-gcc6.  Setting these variables
  explicitly keeps GCC's build from having to guess.
- Pull patches from freebsd6-gcc instead of powerpc64-gcc.
- Use per-arch plists.
- Simplify the post-install steps to keep the hard links the
  normal install performs and avoid renaming binaries.
  Keep links to 'cc' and 'c++'.
