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 use variables with no prefix (such as
dnl CC, CFLAGS, etc.) for the host type as well as the build type,
dnl because GRUB does not need to use those variables for the build
dnl type, so there is no conflict. Variables with the prefix "TARGET_"
dnl (such as TARGET_CC, TARGET_CFLAGS, etc.) are used for the target
dnl type.
