[Buildroot] [PATCH] Permit building grub with an external toolchain.

[Clark Rawlins <clark.rawlins@escient.com>]

Okay,

I've started looking at this but it isn't clear to me how to handle the
following:

$(GRUB_DIR)/$(GRUB_BINARY): $(GRUB_DIR)/.configured
	$(MAKE) CC=$(TARGET_CC) -C $(GRUB_DIR)
	rm -f $(GRUB_DIR)/$(GRUB_BINARY)
	$(MAKE) CC=$(TARGET_CC) CFLAGS+=-static -C $(GRUB_DIR)/grub grub
	mkdir -p $(dir $(STAGING_DIR)/$(GRUB_TARGET_BINARY))
	mv $(GRUB_DIR)/$(GRUB_BINARY) $(STAGING_DIR)/$(GRUB_TARGET_BINARY).static
	$(MAKE) CC=$(TARGET_CC) -C $(GRUB_DIR)/grub

This builds everything dynamically linked first then builds the grub binary statically.
Is the right way to do this to override the target after/before calling the autotools macro?
