[CRIU] [RFC] Build-related changes

[Christopher Covington]

Hi,

The following patches are a mix of fixes I've needed to build in my
environment (Ubuntu x86_64 host, Linaro cross compilation toolchains,
BusyBox core utilities, heavy CFLAG usage) and improvements. The
patches are roughly ordered from what I think are generally useful
and could be merged soon in the beginning of the set to patches that
are maybe just discussion points for now towards the end.

Regards,
Christopher
