Bug#701510: sfst: FTBFS on powerpcspe

Package: sfst
Version: 1.2.0-1.2

Hi,

sfst FTBFS on powerpcspe[1] like this:

[...]
checking whether make sets $(MAKE)... yes
checking Compilation architecture: PPC, i686, x86_64, Other... PowerPC
checking for powerpc-linux-gnuspe-g++... powerpc-linux-gnuspe-g++
checking for C++ compiler default output file name... 
configure: error: C++ compiler cannot create executables
See `config.log' for more details.
make: *** [config.status] Error 77
dpkg-buildpackage: error: debian/rules build gave error exit status 2
[...]

I'm attaching a patch that fixes this by only adding the -maltivec option on
"normal" powerpc, not in the powerpcspe case.

An additional autoreconf is necessary.

Thanks in advance,

Roland
