build: Use separate CFLAGS for tools

Sharing the same CFLAGS for both the firmware and host tools is not
useful and can lead to compilation failure when CFLAGS is set on the
command line.

This patch make MAKEOVERRIDES special variable empty so make's command
line variable definitions are not implicitly forwarded to sub make
invocations. However, make options are still forwarded like "-s" option
to make the build silent.
