Is there any framebuffer testcases?

As I posted a few messages back, based on what symbols were missing when I
did  a link on "whole library" libc.a and crt0.o, these were undefined that
wouldn't
come from libgcc*

_Mutex_Acquire
_Mutex_recursive_Acquire
_Mutex_recursive_Release
_Mutex_Release
posix_memalign

They need to be in newlib/libc/sys/rtems/crt0.c.

It would be nice to have a repeatable way to check for missing symbols in
the
dummy crt0.c. I think my procedure was close but not 100%.
