Crosscompiling again...

Hello,

Im trying to crosscompile a c++ shared Library for a Mips target
System using libtool.
Unfortunately linking fails, because of libtool trying
to link against "/usr/lib/libstdc++.so", which is the X86 Version
of the Library, not the Mips one.

Is there a way to tell libtool not to use the system's standard
library paths? Adding -L<libdirectory> doesn't work. Setting the
environment variables "LIBRARY_PATH/LD_LIBRARY_PATH" also has no 
effect.

Libtool version used is 1.5.2

Regards,
