I think something is wrong with how gmp got configured. What options
did you give to configure? What is the output of

egrep -A1 'M4|CCAS|^\.[a-z]*\.[a-z]*' mpn/Makefile

This is what I get:

/bin/sh ../libtool --mode=3Dcompile --tag=3DCC ../mpn/m4-ccas --m4=3D"m4"
/usr/bin/gcc -std=3Dgnu99 -c -DHAVE_CONFIG_H -I. -I. -I..
-D__GMP_WITHIN_GMP -I.. -DOPERATION_`echo add_n | sed 's/_$//'`
-m32 -O2 -pedantic -fomit-frame-pointer -mtune=3Dcore2 -march=3Dcore2
`test -f 'add_n.asm' || echo './'`add_n.asm

 ../mpn/m4-ccas --m4=3Dm4 /usr/bin/gcc -std=3Dgnu99 -c -DHAVE_CONFIG_H -I.
-I. -I.. -D__GMP_WITHIN_GMP -I.. -DOPERATION_add_n -m32 -O2 -pedantic
