This was for both i386 (native) and s390 (cross), I saw it working
correctly on i386 with the newer version, but don't think it is platform

For gcc-3.0 and 3.2 (unlike 2.95), I get smaller binaries with just
'-mcpu=i386' than with '-mcpu=i686 -malign-functions=0 -malign-jumps=0
-malign-loops=0', so you could just use the former without losing anything
(I suppose, most klibc users will actually have distros based on gcc-3.x).
