Hi!
The nm -u ld.so | cmp -s /dev/null -
test fails on sparc64, because ld.so (and other shared libs) on sparc64
have STT_REGISTER SHN_UNDEF symbols which are supposed to be undefined
per psABI and are not really any kind of errors, just notes about
each library's use of global registers.
Using readelf -s allows us to filter symbols which can be SHN_UNDEF
(symbol 0 and STT_REGISTER).
Ok?

* elf/Makefile ($(objpfx)ld.so): Use readelf -s and awk instead of nm -u
to check for undefined symbols.
