Bobby Powers de28c15daf tools lib api: Undefine _FORTIFY_SOURCE before setting it
Some toolchains (like Hardened Gentoo) define _FORTIFY_SOURCE in the
built-in, default args.  This causes perf builds to fail with:

<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
<built-in>: note: this is the location of the previous definition cc1:
all warnings being treated as errors

To avoid this, undefine _FORTIFY_SOURCE before (possibly re-)defining it
in tools/lib/api.

v2 applies cleanly on top of already pulled kbuild changes for 4.1-rc1.
