[Bug lto/45185] New: Building GCC-4.5.1 for arm-elf

["e0600347 at student dot tuwien dot ac dot at" <gcc-bugzilla at gcc dot gnu dot org>]

I am trying to build 4.5.1 for arm-elf. Although I succeed for 4.5.1 RC
(07-22-2010), the compilation fails for the final release. I have double
checked that I am compiling both versions exactly the same way.

1) export PATH=/data/gcc-arm/arm-elf/bin:$PATH  
2) (build and install binutils 2.20.1 for arm-elf)
3) symlink mpfr-2.3.2 and gmp-4.3.2 into gcc source
4) uncomment lines in gcc/config/arm/t-arm-elf:
 MULTILIB_OPTIONS    += mno-thumb-interwork/mthumb-interwork
 MULTILIB_DIRNAMES   += normal interwork
5) configure with:
../gcc-4.5.1/configure --target=arm-elf --enable-multilib --enable-languages=c
--enable-clocale=gnu --disable-libm --disable-libc --disable-threads
--disable-nls --disable-libssp --disable-intl --with-newlib
--prefix=/data/gcc-arm/arm-elf --srcdir=/data/gcc-arm/wa/gcc-4.5.1
6) build with:
(unset LIBRARY_PATH; unset CFLAGS; make -j 3 && make install)

Results:
gcc-4.5.1-RC-20100722 succeeds, compiles and works perfectly.
gcc-4.5.1 final fails compile with (last lines of build output):
