dnl This configure script is complicated, because GRUB needs to deal
dnl with three potentially different types:
dnl
dnl build -- the environment for building GRUB
dnl host -- the environment for running utilities
dnl target -- the environment for running GRUB
dnl
dnl In addition, GRUB needs to deal with a platform specification
dnl which specifies the system running GRUB, such as firmware.
dnl This is necessary because the target type in autoconf does not
dnl describe such a system very well.
dnl
dnl The current strategy is to build utilities using host
dnl cross-compiler and grub core and modules using target
dnl cross-compiler. For this we use nested packages approach, where
dnl top-level package grub utilities is built with HOSTCC and nested
dnl package (in grub-core directory) builds with TARGETCC.
# NOTE: grub-core/configure.ac must also be updated.
