[patch committed] Fix R_SH_REL32 handling for protected symbol
I've committed the attached one-liner on mainline according to
the patch proposed by Valeriy E. Ushakov to fix a problem for
the protected symbol with SH linker. It's tested with the top
level "make -k check" on sh4-unknown-linux-gnu and glibc build
with no new faiulres.
