Anthony Liguori f80f9ec9a6 Convert machine registration to use module init functions

Paul Brook 1ad2134f91 Hardware convenience library 
The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.

Big/Little endian is not handled because devices should not know or care
about this to start with.

aurel32 007ac6faed target-mips: fix call to check_*() functions 
check_*() functions may in fine call generate_exception(), which ends
by a call to tcg_gen_exit_tb(). As a consequence, we have to make sure
that no TCG temp variables are crossing a check_*() function.
