While building GNU MP 6.1.2 (and 6.1.1) with GCC 5[.4] on a current 
build of the Solaris release in development on a SPARC system, I ran 
across the following error while configuring gmp.

    $ ./configure CC=/usr/gcc/5/bin/gcc CFLAGS=-m64 ABI=64
    checking build system type... sparc-sun-solaris2.12
    checking host system type... sparc-sun-solaris2.12

    checking whether make sets $(MAKE)... yes
    checking whether make supports nested variables... yes
    checking whether to enable maintainer-specific portions of Makefiles... no
    configure: error: ABI=64 is not among the following valid choices: 32

The following patch appears to resolve the issue and the tests run by 
'make check' pass.
