Christophe Leroy 08c18b63d9 powerpc/vdso32: Add missing _restgpr_31_x to fix build failure ...

With some defconfig including CONFIG_CC_OPTIMIZE_FOR_SIZE,
(for instance mvme5100_defconfig and ps3_defconfig), gcc 5
generates a call to _restgpr_31_x.

Until recently it went unnoticed, but
commit 42ed6d56ad ("powerpc/vdso: Block R_PPC_REL24 relocations")
made it rise to the surface.

Provide that function (copied from lib/crtsavres.S) in
gettimeofday.S

Fixes: ab037dd87a ("powerpc/vdso: Switch VDSO to generic C implementation.")
