On Fedora and RHEL the `lld` executable is the plain unversioned `lld`. That's also usable as a linker if it's recent enough. See dotnet/runtime#58959 (comment) for more details and discussion.

Looks good to me as it is. :) |

I think that checking for lld via clang is a better way. We never execute lld directly, so we really care about the one that clang selects by itself. Especially when you have multiple clang / lld versions installed (like I do). Clang seems to always pick lld of the same version. |

We have been carrying the 6.0 version of this patch for RHEL 8 on arm64 here: https://git.centos.org/rpms/dotnet6.0/blob/c8s/f/SOURCES/runtime-arm64-lld-fix.patch
There was an open question about parsing the lld version using clang like so:
Is that worth implementing?
