As can be seen the '/usr/lib/libc.a' is tried to be linked in order to
create the 'shr.o' and then
the 'tmp-libgcc_s.a' from it with 'ar' and finally rename this to
'libgcc_s.a'...
This can be a bug or then the 'sysroot'ed "$sysroot/usr/lib/libc.a"
would be used by the 'nm'.
I didn't use the '--with-sysroot=$sysroot' to point to the (unexisting)
AIX5.3 C library... In a
"traditional" crosscompiler build this would be a serious bug in the
gcc-4.2.2 sources, the
'$tooldir/lib/libc.a' should appear here!
