[MIPS, committed] XFAIL gcc.dg/pr48774.c for MIPS REL targets

[Richard Sandiford]

gcc.dg/pr48774.c fails on MIPS REL targets because of an orphaned
HI16 relocation; see PR 52125 for details.  This isn't a regression,
so I'm just going to XFAIL it for now.

Tested on mips64-linux-gnu and various *-elf targets.  Applied.
