Ah.  I can see how that would be useful.  We have an additional difficulty
in that we support multi-endian targets (mips, arm) so our
solib-absolute-prefix could change from $QNX_TARGET/armle to
$QNX_TARGET/armbe depending on the binary we load.  We already set up our
solib-search-path and s-a-p programmatically and I may have to expand that
logic further to make it all work correctly.
