Which works perfectly well if you remove the full paths and let the
linker search this.

I and others at MontaVista have done a significant amount of work
making HHL into a completely relocatable cross development environment. 
The only big patch left to the tools is to the linker to give
prefix-relative search directories (and GCC-style relocating based on
argv[0]).

We're in the middle of fighting a losing war with libtool.  Right now,
we edit installed .la libraries to remove the full path information
from them.  I might add that, on GNU/Linux, this is entirely adequate;
it would be much simpler if we could get libtool not to generate such
things.  Ditto for DT_RPATH.
