I can reproduce this here, and I think I understand what's going on.
Try this after configuring a cross gcc:
   egrep "STMP_FIXPROTO =|Don't run fix" */*/build-gcc/gcc/Makefile

On architectures I can build, I see e.g.

ppc-405-linux/gcc-3.3-glibc-2.2.5/build-gcc/gcc/Makefile:STMP_FIXPROTO =
stmp-fixproto
ppc-405-linux/gcc-3.3-glibc-2.2.5/build-gcc/gcc/Makefile:# Don't run fixproto
ppc-405-linux/gcc-3.3-glibc-2.2.5/build-gcc/gcc/Makefile:STMP_FIXPROTO =

On sh4, which fails with the current bug, I see e.g.
sh4-linux/gcc-3.3-glibc-2.2.5/build-gcc/gcc/Makefile:STMP_FIXPROTO = stmp-fixproto

So, where's that "Don't run fixproto" come from?

$ find . -type f | xargs grep " 
./gcc/ChangeLog.4:      * config/i386/x-beos (STMP_FIXPROTO): Don't run fixproto.
./gcc/config/t-freebsd:# Don't run fixproto
./gcc/config/t-interix:# Don't run fixproto
./gcc/config/t-linux:# Don't run fixproto
./gcc/config/t-linux-aout:# Don't run fixproto
./gcc/config/t-netbsd:# Don't run fixproto
./gcc/config/t-openbsd:# Don't run fixproto
./gcc/config/cris/t-cris:# Don't run fixproto
./gcc/config/i386/t-beos:# Don't run fixproto
./gcc/config/i386/t-cygwin:# Don't run fixproto
./gcc/config/xtensa/t-xtensa:# Don't run fixproto

That's as far as I've gotten.  I don't really understand
the gcc/config files, but it seems this is where the problem may lie.

OK, learned a little more.  It seems that when building a cross-compiler for ppc,
the Makefile is assembled from the following fragments:

rs6000/t-ppcos t-slibgcc-elf-ver t-linux rs6000/t-ppccomm rs6000/t-rs6000-c-rule

whereas when building a cross-compiler for sh4, the list is

sh/t-sh sh/t-elf sh/t-linux sh/t-le sh/t-monolib

(found by adding set -x to configure, and grepping for dep_tmake_file=).

t-linux contains the magic line 
# Don't run fixproto
STMP_FIXPROTO =

but sh/t-linux doesn't.  Doing the obvious stupid thing --
adding the missing line -- seems to fix the problem.  Patch attached.
Is this proper?

Kaz said:

"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."
