The most basic of testing on x86_64-*-freebsd is showing
some promise

                === gfortran Summary ===

/usr/home/sgk/gcc/obj4x/gcc/testsuite/gfortran/../../gfortran  version 4.6.0 20100909 (experimental) (GCC) 

The 37 failures are do to lto and FreeBSD's libelf.

All of the numeric intrinsic functions give the expected
values.
