The only real bug I am aware of is the "illegal instruction" thing. I
juts built a new version of the distribution with OpenEmbeded and it
still suffers from the same issue - so it is probably not a glibc/gcc
issue but really a kernel problem. But I habe no real idea how/where
to
find that one.
How does the bug show up?
When cross-compiling my first code for the Openmoko Freerunner I had
also copied a new glibc to the device - and that immediately came with
an Illegal Instruction in every shell command... After some analysis
it turned out that my toolchain wasn't configured properly for the
Freerunner CPU (arm4t), i.e. the code did generate a handful of arm5
instructions. What also could be is that some package ./configure may
think they know it better and pass a -mcpu or do other stange things...
Although there are not as many different instruction set variants as
for ARM, there might also be variations. Could that be the same for
the JZ?

On the other hand the IS looks quite simple and straightforward
