grub/genmk.rb
robertmh 15355c7d2f 2009-06-21 Robert Millan <rmh.grub@aybabtu.com>
Fix asm file handling on ELF, and remove workarounds.

        * genmk.rb (class Programs): Detect assembly files, and set ASFLAGS
        and -DASM_FILE=1 appropiately (copied from `class Images' stanza).
        * kern/i386/ieee1275/startup.S (ASM_FILE): Remove macro.
        * kern/i386/coreboot/startup.S (ASM_FILE): Likewise.
