Yes, I do it as part of the regular testing.

You need to remove config.cache and then re-run configure, as the CC value
is cached to be gcc.  I would have CC=cc and make sure the compiler is in
your path.

Also, you need to set FPICFLAGS to -PIC, and -Kpic should be -KPIC.
(I think configure would have figured these out if you had left them

Start again from a clean sheet, edit config.site before you do anything and
it should work. It has for me many times.
