64 bit installation on sparcv9

[Franck MICHEL <Franck.Michel@univ.u-3mrs.fr>]

Hi developpers,

I've tried to install Pari/GP 64-bit version on sparcv9/solaris, but
without success. I've tried different configuration options (in particular
options suggested by Gerhard Niklasch and Igor Schein found in the archives
of this list), but I always failed. 

If you have an idea of options I could try, I'm very interested.

Below details about the machine, and the results of different trials.

Thanks in advance

Installation of Pari 2.2.7:

"Configure / make gp / make install" installs Pari/GP 32 bit version

"Configure --with-gmp / make gp / make install" fails with GMP default
installation (ABI=64):
ld: fatal: file /usr/local/lib/libgmp.so: wrong ELF class: ELFCLASS64

collect2: ld returned 1 exit status
*** Error code 1
make: Fatal error: Command failed for target `libpari-2.2.so.7.0.0'

but works with an ABI=32 installation of GMP. It still installs a 32-bit
version of Pari.
