Same comments as first part of the patch set.

Personally, I'd put the .Lweak_atexit label inside _LITE_EXT ifdefs,
but this matches the way that the ARM port does it, so should be OK
also.

To be fully effective, this requires build script changes to the
github riscv/riscv-gnu-toolchain project, which will be handled as a
separate patch.
