Soalris 10 x86 build issues

[Reginald Beardsley]

A couple of minor glitches:

libgmp.so is specified twice for "make check" targets:

gcc -std=gnu99 -O2 -pedantic -m64 -mtune=k8 -o .libs/t-constants t-constants.o  ./.libs/libtests.a /app/pkgs/gnu/gmp/4.3.2/src/.libs/libgmp.so ../.libs/libgmp.so  -R/app/pkgs/gnu/gmp/4.3.2/lib
ld: warning: file ../.libs/libgmp.so: linked to /app/pkgs/gnu/gmp/4.3.2/src/.libs/libgmp.so: attempted multiple inclusion of file 

There's also a problem w/ finding the correct library for the gcc rruntime.  It's fixable w/ LD_LIBRARY_PATH, but it would be helpful if you didn't have to diddle LD_LIBRARY_PATH to run check for both 32 and 64 bit versions.

Have Fun!
