Has someone written up a draft psABI that defines weak symbol behaviour?
Or better, a draft gABI?  gABI on www.caldera.com is still 24 April 2001.

Also, if ld follows the new semantics, which versions of glibc will no
longer build?  Not that this should deter us from changing ld, but we'd
need to mention in release notes that older versions of glibc require
older versions of binutils.
