[x86_64] Add support for compilation as an x86_64 binary Currently the only supported platform for x86_64 is EFI. Building an EFI64 gPXE requires a version of gcc that supports __attribute__((ms_abi)). This currently means a development build of gcc; the feature should be present when gcc 4.4 is released. In the meantime; you can grab a suitable gcc tree from git://git.etherboot.org/scm/people/mcb30/gcc/.git 2008-11-18 14:30:37 -08:00			`# Include common x86 headers`

[efi] Use elf2efi utility in place of efilink elf2efi converts a suitable ELF executable (containing relocation information, and with appropriate virtual addresses) into an EFI executable. It is less tightly coupled with the gPXE build process and, in particular, does not require the use of a hand-crafted PE image header in efiprefix.S. elf2efi correctly handles .bss sections, which significantly reduces the size of the gPXE EFI executable. 2009-01-07 02:05:51 +00:00			`SRCDIRS += arch/x86/prefix`
