build: do not _FORTIFY_SOURCE in debug mode
When compiling in -O0, the glibc feature.h ignores _FORTIFY_SOURCE and, in some distributions, throws a #warning, which fails the build. This patch removes -D_FORTIFY_SOURCE in all debug configurations. Change-Id: Ic30229c038353e49ff9419779e082a7083c1ea5f Type: fix Signed-off-by: Mohammed Hawari <mohammed@hawari.fr>
