rework architecture / embedded systems concept

Make configuration of new targets cheap.
Just add a new file in target/arch/sys-enabled/foo.
See other files for syntax. While doing runtime tests
with the new infrastructure I've updated a lot of other
stuff:
- gcc 4.5.2
- uClibc 0.9.32-rc1 (NPTL)
- strongswan, php, miredo, parted, util-linux-ng, e2fsprogs

I promise, this is the last big fat commit this year ;)
