[PATCH] fix target/10331: [x86 -> SH] can't compile c++ crosscompilerpart of gcc crosscompiler for sh-elf

AFAIK, fixproto arranges ANSI, POSIX and C++ compatible header files
with adding appropriate prototypes from given soruce directories
including standard header files and it's for the system with broken
header files. So linux usually doesn't need to run it. I can't
reproduce the problem on my systems, but since we (sh-linux folks)
used several different set of header files, fixproto could cause
the problem on some systems.
Your change seems to be safe and 3.4 already uses gcc/config/t-linux
which nullifies STMP_FIXPROTO, so the patch is OK for 3.3 as an
regression fix on sh-linux target. Thanks.
