I guess that you could still use the cross-compilation trick - bring the
library from the target machine to your build machine and change the
search paths (probably manually - using "-s" option and playing with the
generated script.res before running the created ppas.sh) before linking.

Some more tips (just ideas): Only IDE (fp) should be using libc (assuming
we talk about Linux target), so only building that one on the target
machine (make all in the IDE directory) should reduce the building time.
Finally, it might be possible to build everything on the build machine
(again use -s option when building, remove all "rm" commands from the
generated ppas.sh before running it and possibly skip the linker too),
transfer everything to target machine and relink there.

Possibly. You might try it with debug info (and line info) enabled binary
to get backtrace. That might possibly help to shed some light on what's
happening there at least; of course it doesn't automatically mean that it
gets resolved, but there's a chance.
