autogen.sh script generates files under crypto/arch/* that are not currently covered by .gitignore

[nak3]

When running the following commands:

$ git clone https://github.com/libressl/portable.git
$ cd portable
$ ./autogen.sh

Files are generated in crypto/arch/*/*, but these files are not listed in .gitignore.

$ git status
On branch master
Your branch is up to date with 'origin/master'.

	crypto/arch/arm/
	crypto/arch/hppa/

	crypto/arch/powerpc/
	crypto/arch/powerpc64/
	crypto/arch/riscv64/
	crypto/arch/sh/
	crypto/arch/sparc64/

At first, I thought of simply adding them to .gitignore, but when I looked at https://github.com/libressl/portable/tree/master/crypto/arch, I noticed that only loongarch64 and mips are under version control, which confused me — so I decided to open an issue.

loongarch64 and mips are under version control in portable because these aren't supported by OpenBSD natively, but there was interest in using libressl on these architectures. So I think we should ignore crypto/arch/* and add an exception !crypto/arch/loongarch64 next to the one that is already there for mips.

Ah, I understand. Thank you for the explanation.
