This changes to build system to use thin archives rather than
incremental linking for built-in.o, similar to recent change to Linux.
built-in.o is renamed to built-in.a, and is created as a thin archive
with no index, for speed and size. All built-in.a are aggregated into
a skiboot.tmp.a which is a thin archive built with an index, making it
suitable or linking. This is input into the final link.
The advantags of build size and linker code placement flexibility are
not as great with skiboot as a bigger project like Linux, but it's a
conceptually better way to build, and is more compatible with link
time optimisation in toolchains which might be interesting for skiboot
particularly for size reductions.
Size of build tree before this patch is 34.4MB, afterwards 23.1MB.

p9_stop_api's are used to set SPR state on a core wakeup form a deeper
low power state. p9_stop_api uses low level platform formware and
self-restore microcode to restore the sprs to requested values.
Code is taken from :

In the days of yore libpore was closed source and people wanted the
option to not use it. That's no longer the case so lets ditch all
the #ifdef crap.
