FORTIFY_SOURCE requires that optimization is enabled, and causes build
to fail when it isn't. For example, from config.log:
configure:12459: checking for signalfd
configure:12459: gcc -o conftest -Wall -O2 -D_FORTIFY_SOURCE=2 -Werror -Wextra
-Wno-unused-parameter -Wno-missing-field-initializers
-Wdeclaration-after-statement -Wmissing-declarations -Wredundant-decls
-Wcast-align -DG_DISABLE_DEPRECATED -O0 -g conftest.c >&5
