GCC on FreeBSD/ia64: No rule to make target .../libgcc/crtfastmath.o

[Gerald Pfeifer]

Anton reports that GCC fails to build on FreeBSD/ia64.  Any ideas
on what to try?  I assume it's just a small change that caused this
regression (this used to work some releases ago).

gmake[4]: Entering directory `/usr/ports/lang/gcc46/work/build/gcc'
gmake[4]: *** No rule to make target `/usr/ports/lang/gcc46/work/build/ia64-portbld-freebsd9.0/libgcc/crtfastmath.o', needed by `T_TARGET'.  Stop.

Interestingly, i386/* does not show any changes on the i386 side that
look like adjustments along these lines.  Is this something ia64-specific?
Any pointers, suggestions?

I'm sure Anton will be happy to test any patches that one of us may come
up with.
