On SVR4-derived platforms, the character `/' is treated as a comment
character, which means that it cannot be used in expressions. The
`--divide' option turns `/' into a normal character. This seems to be
needed with our local build of binutils since we don't yet use the
internal assembler/disassembler of the Clang tooling.

Alphabetise headers and remove any #if CONFIG_ guards around them.
Background rational:
Remove guarding the inclusion of headers based on CONFIG_ options. This
*potentially* could hide issues such as functions being swapped from
under our feet, since different runtime behaviour could be declared with
the same function same name and type-signature. Hence, depending on the
header we happen to get may change runtime behaviour.
