[klibc] [PATCH] klcc compatibility with gcc

[Erik van Konijnenburg]

This patch addresses three issues in klcc:

 * lets klcc define __KLIBC__.
   It's also defined in the klibc <stddef.h>, but we cannot
   rely on stddef being included in every sourcefile of
   every application that wants to use klibc.
 * supports the option -include,
   for example 'gcc -include config.h expr.c'.
   This option is used in the ash Makefile.
 * when running 'klcc -o app main.o lib.o'
   only the last file was passed to the link-editor.

Regards,
Erik
