libiberty/configure.in and --enable-multilib

[Gunther Nikl]

Hello!

I have run into a multilib problem when configuring with build != host with
3.3 and mainline. libiberty/configure.in adds "--enable-multilib" to the
configure args for the build-libiberty. There is a comment that looks
strange:

   "We need multilib support, but only if configuring for the target"

This comes from egcs and was commited by law (Jeffrey Law) as v1.3. Why
is --enable-multilib added to the configure args? I get a configure abort
because on FreeBSD 4.x the system compiler says it has multilib support
but infact this multilib support isn't there at all.

Thank you,
Gunther Nikl
