    util/xcompile/xcompile: Allow to override `HOSTCC` variable
    
    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.
