Could you please be more specific than "ran into snag" ? Which error
messages and issues, when trying what exactly ?

Because grub2 is kind of special: it needs to build both some things
for the target, and some things for the host. And there are some
explanations about it in grub2.mk:
===
# Grub2 is kind of special: it considers CC, LD and so on to be the
# tools to build the native tools (i.e to be executed on the build
# machine), and uses TARGET_CC, TARGET_CFLAGS, TARGET_CPPFLAGS to
# build the bootloader itself.
GRUB2_CONF_ENV = \
$(HOST_CONFIGURE_OPTS) \
CPP="$(HOSTCC) -E" \
TARGET_CC="$(TARGET_CC)" \
TARGET_CFLAGS="$(TARGET_CFLAGS)" \
TARGET_CPPFLAGS="$(TARGET_CPPFLAGS)"
===
And it is actually more logical for grub2 to be a target package: the
main purpose of grub2 is to have a bootloader on the target, much like
U-Boot or Barebox. The fact that in addition Grub2 provides a bunch of
host utilities is kind of a "detail".
Again, please be more specific about the issues you encounter. At least
please give the detailed steps to reproduce them.
Thanks,
Thomas
