If it was the default version, linker would certainly not be happy at all,
but apparently if it is non-default version, it might work.
In that case, it would make sense to change the IA-64 bits the same way
(though I think we should keep divdi3.c as it should be more efficient than
what libgcc has). Currently e.g. __divtf3 is compiled into glibc twice
on IA-64, once for the export and once hidden, since for the export it
is not the default version and thus linker puts in libgcc.a too.
