Hi Thomas,

The specific attributes for the _start entrypoint are duplicated for each architecture. Deduplicate it into a dedicated #define into compiler.h. This make the code shorter and will make it easier to adapt for clang compatibility.
For clang compatibility, the epilogue will also need to be adapted, so move that one, too.
I'm fine with the general approach, however I think that if we start to add specific attributes and macros like this, we should prefix them with "nolibc" to make sure they won't collide with userland.
Ack.
FYI for v2 I intend to rename the macros to __nolibc_naked, as I have a followup series that needs them also for the non-entrypoint asm functions in arch-x86_64.
Thanks, willy
