RFA: Remove -rpath-link from MIPS, SH, mn10300 Linux targets

[Daniel Jacobowitz]

These targets all use -rpath-link %R/lib:%R/usr/lib.  This was originally
added before ld supported --with-sysroot; but now that it does, I would like
to drop it.  It isn't necessary any more, and it gave me a nasty surprise to
find out that changing the linker script was not enough to make another
directory be searched before /lib for DT_NEEDED entries.

OK?
