Subject: [PATCH trace-cmd] Makefile: Ensure _GNU_SOURCE really is always defined

When CLFAGS is set with a command argument a normal variable
assignment is not sufficient to ensure that _GNU_SOURCE will be
defined. Since this really is critical for building, use an
override directive when adding it to CFLAGS to ensure that it
really does get defined in all cases.
