commit: http://git.buildroot.net/buildroot/commit/?id=9b0e9c83022deac95c85d8f7526b16e420f0b6c8
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Ptrace support detection is ignored when CFLAGS is set by
buildroot. Use override in Makefile to add -DWARN_NO_PTRACE and
-DNO_PTRACE in CFLAGS if ptrace is not available.
