Actually, it looks like you set CFLAGS to an empty string instead of not 
setting it at all. Your compiler produces 64 bit binaries by default, and 
your CFLAGS prevents gmp from passing it the -m32 flag. And you seem to 
have set ABI=32 (or your system is 32 bits), so it does not try 64 bits.

Well, that's just a guess, but it may contain enough hints to fix the 
issue.
