Hi,

with PKGSRC_COMPILER=gcc on IRIX64 6.5 there were constantly warnings
like

	unknown flag R/path/to/lib (ignored)

Most stuff worked nonetheless, however ldd shows links into the pkgsrc working
object directory, so those will break as soon as I clean that. Others use only
base libraries in the default library path, so for those there wasn't a
problem.

GCC on IRIX still uses the native linker under the hood, so -R does not work.
The flag used by the MIPSPro compiler should be used for GCC as well. This
should not break anything unless someone uses GNU ld on IRIX, I think.

Are there any objections against the following change?
