[PowerPC64LE] Rust powerpc64le port

[mikael]

Summary

The changes are based on a -nightly patch I was working on locally.

Upstream progress:

• patch-vendor_openssl-src_src_lib.rs has already been upstreamed.
• patch-src_llvm-project_clang_lib_Basic_Targets.cpp has already been upstreamed (but did not land in LLVM 11)

FWIW,

• @tobik is inactive after rP550400, so better use rust group.
• Rust 1.47 is expected (calendar, pre-release) in a few days, requiring to test powerpc64le again

Can you show the error? armv7 doesn't exist on FreeBSD 11 and powerpc64le doesn't exist on FreeBSD 12.

OK, sure, I can reroll when 1.47 is out if you like.

I *think* the reason for these is to auto-exclude things from the bulk builds.

But yeah, I suppose neither of the IGNORE_ lines are very relevant given there aren't branch builders for them in the first place.
