unrecognized option '--subsystem'

[ElvishJerricco]

After failing to build with EDK II (#10), I am now failing to build with GCC and make:

./set_grub_cpu.sh X64
make ARCH=x64 CROSS_COMPILE=x86_64-linux-gnu- -j 8 -l 8

And getting this error on both the latest release and on master.

[LD] btrfs_x64.efi
GNU ld (GNU Binutils for Debian) 2.28
  Supported emulations:
   elf_x86_64
   elf32_x86_64
   elf_i386
   elf_iamcu
   i386linux

   elf_k1om
   i386pep
   i386pe
/usr/bin/ld: unrecognized option '--subsystem'
/usr/bin/ld: use the --help option for usage information

Don't use -j and don't use CROSS_COMPILE= for x64:

@pbatard If I don't use CROSS_COMPILE, I get which: no x86_64-w64-mingw32-gcc.

[pbatard]

Then you need to install that one. I may have forgotten to mention it in the README.

[ElvishJerricco]

@pbatard Why? Why wouldn't the Linux one work? Surely this is platform agnostic.

[pbatard]

Not it's not. EFI x86 binaries are basically Microsoft Windows DLLs, so you need something that can produce Microsoft-like code, which MinGW can, but vanilla gcc can't (at least when gnu-efi is being used).

[ElvishJerricco]

Ahh. Odd, but ok.

[ElvishJerricco]

And yea, that did fix it for me, thanks.

[pbatard]

Cool. I'll make sure to update the README when I get a chance. This is only needed for ia32/x64 though. arm/aa64 don't need MinGW (obviously).
