Looks interesting. I have never dealt with LXC, but I'll have a look.

Can you comment on the issue regarding the missing syscall 186 on
qemu-sh4? I have modified the qemu source code now to make the
sigaltstack syscall available on sh4 as well and it appears to
me that this syscall is not architecture-specific but I am not
sure. At least according to the kernel sources, 186 maps to the
same syscall on sh32 and sh64 as it does on other architectures.
I have rebuilt the qemu version from unstable now (1:2.4+dfsg-4),
backported it to jessie and added TARGET_SH4 to the list of
architectures which has sigaltstack. I did my first test build
by successfully building xbill on qemu-sh4 with gcc-5 and I
can install and run the game fine on my SH7785LCR board.
Any comments? Can we merge this patch (see attached)?
