Hi

Does it update config.sub and config.guess, I know it's already
stage 4, but the config.* stuff update should be harmless things,
and we need this for RISC-V big-endian support, which is already
supported in binutils 2.36.

This imports from:

sha1 6faca61810d335c7837f320733fe8e15a1431fc2

ChangeLog:

	* config.guess: Import latest upstream.
	* config.sub: Import latest upstream.
