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

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).
