mips64 ld GOT problem

Hi all:
I have been trying to bootstrap clang/llvm 3.5 for mips64 (i.e. cross build clang/llvm 3.5 for mips64 using clang/llvm 3.5) but run into the following linker problem (see below) in about the midway point as it is trying to link 'opt'. The assertions that fail are the following:
BFD 2.17.50 [FreeBSD] 2007-07-03 assertion fail /usr/home/sson/freebsd/gnu/usr.bin/binutils/libbfd/../../../../contrib/binutils/bfd/elfxx-mips.c:7455
BFD_ASSERT (g->assigned_gotno - g->local_gotno
<= g->global_gotno);
BFD 2.17.50 [FreeBSD] 2007-07-03 assertion fail /usr/home/sson/freebsd/gnu/usr.bin/binutils/libbfd/../../../../contrib/binutils/bfd/elfxx-mips.c:2767
/* There should have been enough room in the symbol table to
accommodate both the GOT and non-GOT symbols. */
BFD_ASSERT (hsd.max_non_got_dynindx <= hsd.min_got_dynindx);
BFD 2.17.50 [FreeBSD] 2007-07-03 assertion fail /usr/home/sson/freebsd/gnu/usr.bin/binutils/libbfd/../../../../contrib/binutils/bfd/elfxx-mips.c:10282
/* Make sure we didn't grow the global .got region. */
dynobj = elf_hash_table (info)->dynobj;
got = mips_elf_got_section (dynobj, FALSE);
g = mips_elf_section_data (got)->u.got_info;
if (g->global_gotsym != NULL)
BFD_ASSERT ((elf_hash_table (info)->dynsymcount
- g->global_gotsym->dynindx)
<= g->global_gotno);
Does anyone have an idea for a work around or fix?
Thanks in advance,
-stacey.
