  All of these files either #include <system.h> directly or #include "libelfP.h"
And now "libelfP.h also #include <system.h>, so the platform depended include
can be moved to system.h safely

I like this in theory since it cleans up some of the includes.
But it doesn't work as is.

libebl/eblobjnotetypename.c only included system.h so now doesn't
compile anymore.  And libintl.h is removed from libelf/elf_error.c
which really is necessary.

Cheers,

Mark

OK, updated in v2
