Thanks, Ross I had modified the makefile like what you said and now it works fine.

So your makefile is explictly saying "ignore the value from the
environment, always use gcc on the host".

Delete that line from the makefile, the default is good and then the
environment value to set CC to the cross compiler will work.

This is why people shouldn't hand-code Makefiles: it is harder than it
looks.  This makefile probably isn't respecting CFLAGS/LD/LDFLAGS
either.
