   Really?  SGI does this?  I'm a bit surprised.

It actually follows from a careful reading of the SVR4 generic ELF
ABI.  The GNU linker originally behaved this way as well.  However,
somebody complained, and I checked Solaris.  Since Solaris acts
differently, I changed the GNU linker, thus unfortunately perpetuating
a split.
