Package: gcj-4.7

Hi,

gcj-4.7 currently FTBFS on powerpcspe[1] like this:

/PKGBUILDDIR/build/./gcc/xgcc -B/PKGBUILDDIR/build/./gcc/ -B/usr/powerpc-linux-gnuspe/bin/ -B/usr/powerpc-linux-gnuspe/lib/ -isystem /usr/powerpc-linux-gnuspe/include -isystem /usr/powerpc-linux-gnuspe/sys-include    -g -O2 -O2  -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition  -isystem ./include   -fPIC -mlong-double-128 -mno-minimal-toc -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector   -fPIC -mlong-double-128 -mno-minimal-toc -I. -I. -I../.././gcc -I../../../src/libgcc -I../../../src/libgcc/. -I../../../src/libgcc/../gcc -I../../../src/libgcc/../include -I../../../src/libgcc/../libdecnumber/dpd -I../../../src/libgcc/../libdecnumber -DHAVE_CC_TLS  -o crtresfpr_s.o -MT crtresfpr_s.o -MD -MP -MF crtresfpr_s.dep -DSHARED -c -xassembler-with-cpp ../../../src/libgcc/config/rs6000/crtresfpr.S
../../../src/libgcc/config/rs6000/crtresfpr.S: Assembler messages:
../../../src/libgcc/config/rs6000/crtresfpr.S:42: Error: Unrecognized opcode: `lfd'
[...]

Seems that some asm instructions for powerpc don't apply to powerpcspe.

Turns out that the same patch that fixed a similar issue for gcc-4.7 also
applies here. Re-attaching.

Thanks,

Roland
