I have no problem with using 'ld -z defs' on libm and whatnot
other than libc.  Would be nice for libc (we used to have a
script that performed a similar function) but sadly it does
indeed whine about missing main, and we can't add even a weak
main to libc or badness will ensue.  Might be possible to link
libuClibc twice, with a script wrapping up ld and filtering
stdout for 'main' and only emitting an error for additional
output....
