[OpenAFS] How to set CFLAGS for OpenAFS?

[Evan Knop]

I'm trying to build OpenAFS with a certain set of CFLAGS.  Is there a 
string I can pass to configure to add something to the CFLAGS for each 
directory (in this case, its -fPIC so the .a files can be linked into a 
.so library for PAM on x86_64/amd64).

I've found that the openafs-1.2.11-rhel3.0.1.src.rpm is missing a few 
things for x86_64, which will cause a rpmbuild -ba to go quite wrong. 
Would there be an interest in my patches when I've got everything working?

Currently, I've had to disable building with PAM because of -fPIC 
problem, but I have managed to build the rest of the rpms (minus the 
krb5support) successfully.  The two major changes I've needed were to 
translate the "arch = x86_64" to a sysbase of "amd64", and to set 
LINUX_GCC_KOPTS="-mno-red-zone" before all the ./configure steps.

Thanks!
