The symbol _ITM_malloc is in libitm. Maybe the problem is an extra

Actually, I think the missing symbol is
___emutls_v._ZN3GTM12_gtm_thr_tlsE
and (although the m32 lib builds OK - the symbol is also missing
there).
The m64 build fails because of the -Wl,-undefined -Wl,dynamic_lookup
FAOD, Is there some reason that this library needs to resolve symbols
from some external source at load time?
in combination with the missing var.
the m32 build succeed - but none of the testsuite runs, because the
emutls var is missing (not resolved at load).

... I strongly suspect it might be another manifestation of:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50598
This is confirmed - if I hack around that bug, the library builds.
There are two other issues I can see so far:
1/ the symbols generated in sjlj.S are not getting their extra "_" (I
patched that up temporarily manually) ... which allows some of the
testsuite to pass.
2/ The section .tm_clone_table doesn't exist for Darwin leading to
assembler errors because ".tm_clone_table" is not a complete section
spec for Darwin
(that's not too hard to fix - but too late for tonight).
