I am seeing this failure when bootstrapping. It worked for me last week:

Did you update GMP or MPFR in the last week?
From:
http://www.mpfr.org/faq.html
When I link my program with MPFR, I get undefined reference to __gmpXXXX.
Link your program with GMP. Assuming that your program is foo.c, you should
link it using: cc link.c -lmpfr -lgmpMPFR library reference (-lmpfr) should be
before GMP's one (-lgmp). Another solution is, with GNU ld, to give all the
libraries inside a group: gcc link.c -Wl,--start-group libgmp.a libmpfr.a
-Wl,--end-group See INSTALL file and ld manual for more details.
Moreover, if several GMP versions are installed (e.g., one provided by the
system and a new one installed by some user), you must make sure that the
include and library search paths are consistent. Unfortunately, on various
GNU/Linux machines, they aren't by default. Typical errors are: undefined
reference to `__gmp_get_memory_functions' in make check when GMP 4.1.4 is
installed in /usr/{include,lib} (provided by the system) and GMP 4.2.1 is
installed in /usr/local/{include,lib} (installed by the user with configure,
make, make install).

Good point. I should have figured that out.
I love this gmp/mpfr requirement. You keep reminding me, but after
about two weeks I forget and it bites me again.
Thanks,
