[PATCH] tools lib symbol: Use -D_FORTIFY_SOURCE=2 for non-debug builds

[Uwe Kleine-König]

Commit 160be157eaba ("tool lib symbol: Add Makefile/Build") failed to
define _FORTIFY_SOURCE to 2, probabaly this was cut&pasted from other
Makefiles with the same problem.

Fixes: 160be157eaba ("tool lib symbol: Add Makefile/Build")
