Libtool only passes through options that it understands.  Otherwise 
one must use -Wc, and -Wl, syntax to pass options to the compiler or 
linker.

Also, usually cross-tools are supposed to be named a particular way 
(including the target triplet in the name) according to autoconf 
conventions (see the autoconf documentation).  This helps autoconf and 
libtool understand that cross-compilation is being performed, and 
assures that the correct tools are used.

On a system here, I see cross tools named like mips-linux-gcc and 
mips-unknown-linux-uclibc-gcc.
