[ipxe-devel] [PATCH] [build] Add HOST_WORKAROUND_CFLAGS

[Geoff Levand]

To support cross compiling the workaround flags need to be split
into host and target flags.

Fixes build errors like these when cross compiling for arm64:

  [HOSTCC] util/elf2efi64
  gcc: error: unrecognized argument in option ‘-mabi=lp64’
  gcc: note: valid arguments to ‘-mabi=’ are: ms sysv
