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!
