What happens if you go completely around libtool, and set SGI_ABI before
you invoke libtool (and then don't pass -64 to anything via CC/CFLAGS

See the ABI(5) man page for more information.

Also, whether or not that works, what happens if you instead do:

CC='cc -64 -Wl,-64'
CXX='CC -64 -Wl,-64'

Do either of these work around the problem successfully?

Ideally libtool should be passing the link flags unmolested, but it's not
(yet) perfect.
