WORKAROUND for gmp 6.0.0 build on Mac OS X 10.4.11, gcc 4.0.1, build 5341

[Michael Jones]

The infamous Mac OS X build 5341 compiler bug (still working on this):

I seem to have found a workaround by capturing the "make check" shell
scripting and through "hacking" and tinkering discovered that if I
drop the "-mtune=970" option the object and binary created do not
return an "Illegal Instruction" error on invocation.  But, now, trying
to find a sophisticated method of doing this via ./configure.
**Note: building on Intel Mac OS X 10.5.8 had no issues!!  But, I need
10.4.11 since I have many apps that have not ported to later editions
of Mac OS X Intel/PPC.  And, I like having f95 and OpenCOBOL available
for PowerPC, since IBM XL Fortran has ceased being "open".
