Hi! media-sound/cdparanoia doesn't compile on cross-compilation between two different arches, because the compiler is simply 'gcc', and not '${CHOST}-gcc'. To fix it, is only needed to export CC with 'tc-export CC' in src_compile(). With the attached patch works to me well between i686, ppc and amd64. Good bye!

This is fixed already.
