Okay now I know why I put those in there for temp-system ppl.

The way ppl detects gmp is different when using --with-gmp compared  
to --with-gmp-include and --wiht-gmp-lib

A lot of users use the same machine for the target build. x86_64 to  
x86_64.

If you do a cross toolchain for another arch, say powerpc or  
powerpc64 or sparc64 then you get issues like this which don't crop  
up when the host can run the target binaries without issue.

checking for the GMP library version 4.1.3 or above... cat: error  
while loading shared libraries: /tools/lib/libc.so.6: ELF file data  
encoding not little-endian

using --with-gmp-include=/tools/include  and --with-gmp-lib=/tools/ 
lib fixes the issue as it isn't attempting to run target arch binaries.

This would have been missed if I didn't build for another arch. Glad  
I ran across it.

Sincerely,
