So you're trying to bootstrap gnat on m68k-linux.  Excellent.  I've tried to do
that myself recently, following my bootstrap of gnat on arm-linux-gnueabi a few
years ago.  The cross-compilation issues are real but can be worked around
manually.  The more serious problem I found is that the final gnat executables
segfault on the m68k target.  Even a trivial 'gnat' w/o options which should
just print a few lines of help text segfaults.  So I fear there's a runtime
issue or miscompilation somewhere.
