[OpenAFS] Linux2.6, Sparc [64], and Gentoo

Hi, I'm attempting to get OpenAFS compiled on Gentoo, kernel 2.6.15, on an
UltraSparc.  My problem *seems* to be that Gentoo doesn't officially support
sparc64 by default (and doesn't have 64-bit mode in the compiler they
supply), and openafs doesn't support linux 2.6 with ordinary 'sparc'.

the first problem is indicated by
gcc -O -I. -I/var/tmp/portage/openafs-1.4.1_rc8/work/openafs-1.4.1-rc8/src/c
onfig -I/var/tmp/portage/openafs-1.4.1_rc8/work/openafs-1.4.1-rc8/include -O
2 -D_LARGEFILE64_SOURCE -m64 -c -o cmd_errors64.o cmd_errors.c
| gcc: -m64 detected on the command line overrides implicit -m32 added by
the wrapper.
| cc1: error: -m64 is not supported by this configuration
| cc1: error: -mlong-double-64 not allowed with -m64
| distcc[12784] ERROR: compile cmd_errors.c on localhost failed
| make[3]: *** [cmd_errors64.o] Error 1

and the second by

> find . -name *linux* | grep sparc

Now, in gentoo they have two ebuilds: one named openafs, and one named
openafs-kernel which appears to just "make only_libafs".  If I let the
gentoo build system to its own configure, I end up with an error about a
missing "param.sparc_linux26".  If I let your autoconf system run naturally,
I end up with a successful configuration that is using sparc64_linux26.
When building "only_libafs" it actually compiles and gives me the kernel
module.  However when doing a normal build, it dies with the compile error

Any suggestions on what I can/could/should do?

BTW, If I rebuild gcc to v3.4 and include 64-bit support, then your build
system should work, but I won't be able to contribute the ebuild because it
wouldn't work for other gentoo users without them also recompiling gcc.
