[Qemu-devel] [PATCH 2/5] roms/edk2: Avoid bashism in script

[Philippe Mathieu-Daudé]

Use the POSIX '=' to evaluate equality.

This fixes building the roms with a dash shell:

  $ make -C roms efi
  [...]
  cp edk2/Build/ArmVirtQemu-ARM/DEBUG_GCC5/FV/QEMU_EFI.fd \
        ../pc-bios/edk2-arm-code.fd
  truncate --size=64M ../pc-bios/edk2-arm-code.fd
  /bin/sh: 111: [: i686: unexpected operator
  /bin/sh: 112: [: i686: unexpected operator
  /bin/sh: 116: [: i686: unexpected operator
