[Qemu-devel] [PATCH v3 2/5] roms: build the EfiRom utility from the roms/edk2 submodule

[Laszlo Ersek <lersek@redhat.com>]

Building the EfiRom utility from "roms/edk2/BaseTools" should make
"roms/Makefile" more self-contained. Otherwise, we'd call the system-wide
EfiRom for building the combined iPXE option ROMs, but call the sibling
utilities from "roms/edk2/BaseTools" for building "roms/edk2" content.
