Description

When building with -O0 passed into do_autogen.sh, the compiler ultimately begins warning of FORTIFY_SOURCE being set and being incompatibly with -O0.

Unsetting FORTIFY_SOURCE in CFLAGS/CXXFLAGS via do_autogen.sh is not enough. It appears that src/Makefile-env.am forces HARDENING_CFLAGS undre an "if LINUX" conditional.

It seems necessary to disable HARDENING_CFLAGS when -O0 is used (either automatically, or knowingly by the user).
