[POWER] Error when trying to compile 32 bit libs on 64 bit machine ...

[mwichtlh at students dot mail dot uni-mannheim dot de]

Hi,

I am trying to cross compile a powerpc 32 bit version of glibc on a  
powerpc 64 machine. Configuration works fine:

[xxx@yyy:glibcbuild] $ ../glibc-2.14/configure

Seems like inline assembly is being compiled wrong. Any workarounds or ideas?
