Probably Libtool needs to be ported fully to this system first, or,
just the name matching be adjusted (libtool matches compilers by their
names).  Can you point us to documentation of the compiler and linker
suite of this system?  Would you be willing to go through the porting
effort with us (you'll have to answer a few questions and try out some
things on this system while we work on a patch).
