gmp 6.2.0 build failure in 32-bit mode on Linux/mips

[Bruno Haible]

Hi,

On a Linux/mips64 (little-endian) machine (gcc23.fsffrance.org),
a build of gmp-6.2.0 in 32-bit mode fails:

$ ../configure CC="gcc -mabi=32" CPPFLAGS="-I/home/haible/prefixel32/include -Wall" LDFLAGS="-L/home/haible/prefixel32/lib"

Makefile:768: recipe for target 'add_n.lo' failed
make[2]: *** [add_n.lo] Error 1

I did not specify an ABI variable to configure, because the documentation
section 'ABI and ISA' does not specify any value values for Linux/mips.
