Subject: util/xcompile/xcompile: Allow to override `HOSTCC` variable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently `xcompile` generates `.xcompile` with the following at the
top.

	# platform agnostic and host tools
	IASL:=iasl
	HOSTCC:=gcc

The assignment `:=` doesn’t allow to override the variable. So use `?=`
instead so the host compiler can be passed to coreboot.

	HOSTCC=gcc-5 make

Note, that this is just a hack, as the existence of `gcc` is checked
beforehand.
