config.mak.dev: squelch -Wno-missing-braces for older gcc
Versions of gcc prior to 4.9 complain about an initialization like:
struct inner { int x; };
struct outer { struct inner; };
struct outer foo = { 0 };
and insist on:
struct outer foo = { { 0 } };
Newer compilers handle this just fine. And ignoring the window even on
older compilers is fine; the resulting code is correct, but we just get
caught by -Werror.
Let's relax this for older compilers to make developer lives easier (we
don't care much about non-developers on old compilers; they may see a
warning, but it won't stop compilation).
