I get test failures on PPC when JIT enabled. We have 64-bit kernel and 32-bit
userspace (-m32 GCC option) and some hardening options enabled (CFLAGS=-O2 -g
-pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m32):
Running JIT regression tests:

I will try to get interractive access to some PPC to see what happens.
Also I will check this code on n32 MIPS64 today evening. pcrejit(3) says
MIPS32. Does it mean pure 32-bit system, or are n32/o32 ABIs supported too?
