I'm not sure if "nm -g" would work under Linux, since

The equivalent of "objdump -T" is "nm -D".
Whatever the 'objdump -T' now tries to do during the
'gcc/configure', that it does with the wrong 'objdump',
that for the $target, not that for the $host !
Maybe there was some usual one-eyeness in implementation,
in a native GCC $host == $target, and it never was thought
that someone could make a cross GCC ?
This "feature" appeared when someone tried to build
gcc-4.5.0 for 'arm-elf' on a x86_64 machine, seemingly
the objdump made for arm-elf target and x86_64-linux-gnu
host doesn't grok 64-bit ELF binaries... Meanwhile on a
32-bit i686-linux-gnu host there is no problem :
[root@Dell gcc]# /usr/local/arm-elf/bin/objdump -T xgcc
xgcc: file format elf32-little
