Subject: [PATCH] perf tools: Do not use _FORTIFY_SOURCE when DEBUG=1 is
 specified

As:

make DEBUG=1 -C tools/perf

disables optimizations and _FORTIFY_SOURCE in recent distros requires
optimizations to be enabled, seen on a Fedora 17 system:

[acme@Fedora17 linux]$ make DEBUG=1 O=/home/acme/git/build/perf/ -C
tools/perf install
