[llvm][Triple] Add libc-less variants of some environments #168042

alexrp · 2025-11-14T11:10:07Z

In Zig, building libc-less binaries is a first-class use case. As such, we would like to have environment names that indicate the ABI but without implying anything about libc. This is in line with the existing EABI and EABIHF environments.
