Note that I also see a number of warnings like:

/usr/bin/sh64-linux-gnu-nm: _sdivsi3_s.o: File format is ambiguous

This behaviour can be produced with the SVNREV 212237 (2014-07-02) gcc-4.9.0
compiler tarball and no extra patches.

The compiler is configured thusly:

AR_FOR_TARGET=/usr/bin/sh64-linux-gnu-ar \
AS_FOR_TARGET=/usr/bin/sh64-linux-gnu-as \
DLLTOOL_FOR_TARGET=/usr/bin/sh64-linux-gnu-dlltool \

--with-multilib-list=m5-32media,m5-32media-nofpu,m5-compact,m5-compact-nofpu,m5-64media,m5-64media-nofpu

The binutils is:
sh64-linux-gnu-as -v
GNU assembler version 2.24.0 (sh64-linux) using BFD version version
2.24.0-4.fc20 20140613

The compiler is built:

AR_FOR_TARGET=/usr/bin/sh64-linux-gnu-ar \
AS_FOR_TARGET=/usr/bin/sh64-linux-gnu-as \
DLLTOOL_FOR_TARGET=/usr/bin/sh64-linux-gnu-dlltool \
LD_FOR_TARGET=/usr/bin/sh64-linux-gnu-ld \
NM_FOR_TARGET=/usr/bin/sh64-linux-gnu-nm \
OBJDUMP_FOR_TARGET=/usr/bin/sh64-linux-gnu-objdump \
RANLIB_FOR_TARGET=/usr/bin/sh64-linux-gnu-ranlib \
STRIP_FOR_TARGET=/usr/bin/sh64-linux-gnu-strip \
WINDRES_FOR_TARGET=/usr/bin/sh64-linux-gnu-windres \
WINDMC_FOR_TARGET=/usr/bin/sh64-linux-gnu-windmc \
make -C sh64-linux-gnu -j12 tooldir=/usr all-gcc

Then libgcc is built:

make -C sh64-linux-gnu -j12 tooldir=/usr all-target-libgcc

Created attachment 33144
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33144&action=edit
Old, no-longer functional patch to libgcc

I was given the attached patch when I was on gcc-4.7 but it doesn't seem to
help with gcc-4.9.  The problem occurs with or without the patch.
