OE needs to be able to change the default compiler. If we pass in HOSTCC
through the make command, it overwrites not only this setting but also the
setting in tools/Makefile wrapped in ifneq ($(CROSS_BUILD_TOOLS),) which
breaks the build.
We therefore add a way of changing the default in the top level Makefile
without interfering with the other setting.
