#7132: mpir-1.2.p7 fails to build as CXXFLAGS has no 64-bit option on Solaris

----------------------+-----------------------------------------------------
I'm using the following hardware and software now.
* A Sun Blade 2000 running Solaris 10 update 7
* Sage 4.1.2.rc0
* gcc 4.4.1
* SAGE64 exported to "yes"
mpir-1.2.p7 consists of both C and C++ code, but although the spkg-install
is adding -m64 to CFLAGS, it is not doing this to CXXFLAGS on Solaris.
Hence it attempts to build with a mix of 32 and 64-bit binaries, which
gives the usual error:
ld: fatal: file .libs/dummy.o: wrong ELF class: ELFCLASS32
quired
A look at the object files, clearly shows some are built 32-bit, whilst
others are 64-bit.
{{{
./cxx/.libs/ismpf.o: ELF 32-bit MSB relocatable SPARC32PLUS Version 1,
V8+ Required
./cxx/.libs/ismpq.o: ELF 32-bit MSB relocatable SPARC32PLUS Version 1,
V8+ Required
./cxx/.libs/osfuns.o: ELF 32-bit MSB relocatable SPARC32PLUS Version 1,
V8+ Required
./cxx/.libs/ismpz.o: ELF 32-bit MSB relocatable SPARC32PLUS Version 1,
V8+ Required
}}}
though others (not shown) are 64-bit as they are supposed to be.
There are a number of packages in Sage building as 32-bit on Solaris,
despite SAGE64 being set to "yes" This include, but are almost certainly
not limited to:
* zlib #7128
* libgpg_error #7129
* libpng #7130
* libcliquer #7131
mpir fails to build at all, since it is trying to mix 32 and 64-bit
objects.
The fix to this will be quite easy, but I will wait until I've written a
better sage-env, which will mean the correct flags for 64-bit will be
generated on all platforms and compilers we can possibly envisage. Whilst
-m64 works with Sun and GNU compilers, it will not work with native
compilers on AIX or HP-UX.
