The security flag '-D_FORTIFY_SOURCE' requires at least -O to work,
otherwise a warning is given. If CFLAGS additionally contains -Werror,
this warning turns into an error. As Openjdk build system intentionally
deoptimizes certains files due to potential bad codegen during
optimization,
build will fail when both '-D_FORTIFY_SOURCE' and '-Werror' are used.
As turning the optimizations back on will likely break things, the
warning is silenced instead.
