I think the important hunk is:

configure:12340: checking whether __float128 is supported
...
/var/tmp//cciKxWc5.o: In function `foo':
/usr/ports/lang/gcc46/work/build/ia64-portbld-freebsd9.0/libquadmath/conftest.c:35:
undefined reference to `_U_Qfdiv'
/usr/ports/lang/gcc46/work/build/ia64-portbld-freebsd9.0/libquadmath/conftest.c:39:
undefined reference to `__divtc3'
/var/tmp//cciKxWc5.o: In function `bar':
/usr/ports/lang/gcc46/work/build/ia64-portbld-freebsd9.0/libquadmath/conftest.c:44:
undefined reference to `_U_Qfmpy'

which means the ia64 __float128 support is not in a good shape, either just on
freebsd, but maybe on anything but hpux.  It is unclear whether _U_Q* are meant
to be provided by ia64 libgcc or libc.
