Disable overflow checks for compiler-builtins

maurer · maurer · commit cfda165e89cf · 2021-04-26T11:55:19.000-07:00
Similar to how compiler-builtings has panic forced to abort, it must
also have overflow checks disabled. Panicking is not available at that
stage, so attempting to build with a global default of overflow checks
enabled will fail.
