linuxptp: don't check host headers for target features

The incdefs.sh script runs ${CROSS_COMPILE}cpp to get a list of default
headers directories. Make sure CROSS_COMPILE is set correctly to avoid check
of host headers.

Also, drop the CC command line override. Upstream makefile sets CC to
$(CROSS_COMPILE)gcc.

Should fix:
