// With GCC, -fasynchronous-unwind-tables emits full .eh_frame and no
// .debug_frame. Just -fno-unwind-tables is actually independent and
// doesn't negate the default -fasynchronous-unwind-tables. However,
// -fno-asynchronous-unwind-tables -fno-unwind-tables not only makes it
// emit .debug_frame instead of .eh_frame but also makes it emit partial
// (call-site-only) .debug_frame. Since GCC just emits `.cfi_*` asm
// directives and doesn't otherwise emit its own `.cfi_sections`, we can
// just inject one early here (see kernel/debug-frame.S for where the
// corresponding trick is done for assembly files).
