Yes, I do, per Joseph S. Myers' instructions:

I recommend using GNU as and Sun ld. /usr/sfw/bin/as should be a suitable
version of the GNU assembler, or try the 2.15.97 binutils snapshot (from
ftp://gcc.gnu.org/pub/binutils/snapshots/) for an assembler which should
also be sufficiently recent [..]

Note that no other combination will even bootstrap. GNU ld stumbles
upon a Sun-supplied crt*.o file, and Sun's as chokes on the generated
assembly (x86_64 instructions it fails to handle?).
