building the trunk fails on x86_64-unknown-linux-gnu as of r130396. The failure
occurs while building fixincl. The compilation is done in 64 bit, but the link
stage in 32 bit, which of course fails:
gcc -c -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes
-Wold-style-definition -Wmissing-format-attribute -Wno-overlength-strings

Note the explicit -m32 during the link stage.
A possibly related issue is that the configure script now explicitly checks for
32-bit versions of the MPFR and GMP libraries, also by adding a -m32 flag to
the compilation of the test program.
