It worked (somehow, not quite correct, and some packages where not
rebuildable) at the time where uClibc had support for LIBGCC_FUNCTIONS
(adding functions from libgcc to libc) This was the only way I got a
system running it (__guard and __smash... where added to libc). Since then
I cannot modify buildroot so that I get a system running, segfaults on all
the line (tested only with gcc-3.3.x and protector 3.3-5). I think the
solution would be to add the needed functions to uClibc (and remove them
from libgcc!!!).

UPX developer says, that the uncompression does not cost much, didn't
really tested it. I do not have cramfs experience.

The wrappers are for ever gone. Use the procedure from buildroot (the
toolchain building from here).
