[Buildroot] [git commit] linuxptp: don't check host headers for target features

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=85bf5750fe6415949cdd4e6ab27ed02f88f47d1e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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:
