That test helped me get further along in the GCC bootstrap, but I'm now
failing to link the 64-bit libgomp.so:

gold-2.21.51: fatal error: .libs/team.o: readv failed: Invalid argument

With truss, I see that readv is called like this:

11626:  readv(21, 0x080438E4, 17)                       Err#22 EINVAL
11626:          iov_base = 0xFE809CA0  iov_len = 2807
11626:          iov_base = 0x080418E4  iov_len = 33
11626:          iov_base = 0xFE80B9A8  iov_len = 41
11626:          iov_base = 0x080418E4  iov_len = 15
11626:          iov_base = 0xFE80A7A0  iov_len = 71
11626:          iov_base = 0x080418E4  iov_len = 1
11626:          iov_base = 0xFE80D8E0  iov_len = 8
11626:          iov_base = 0xFE80A7F0  iov_len = 14
11626:          iov_base = 0x080418E4  iov_len = 2
11626:          iov_base = 0xFE80D8F8  iov_len = 8
11626:          iov_base = 0xFE81A858  iov_len = 4666
11626:          iov_base = 0xFE824120  iov_len = 1059
11626:          iov_base = 0xFE830BE8  iov_len = 5233
11626:          iov_base = 0xFE83B4FE  iov_len = 464
11626:          iov_base = 0xFE8369D6  iov_len = 1156
11626:          iov_base = 0x080418E4  iov_len = 2494

i.e. iovcnt is 17, but iov[] has only 16 members.  Seems inconsistent to
me, though this could be a truss artefact.
