Subject: [PATCH] Allow setting the commit id using /p:LatestCommit
This is similar to how CommitCount is already supported.
This lets consumers who are building outside a git repo, such as
source-build, set a commit id which is displayed by `dotnet --info`
and `strings dotnet | grep '@(#)'`.
See: https://github.com/dotnet/source-build/issues/651

Subject: [PATCH] Fix compilation with -fno-common.
Making all other archs consistent with IA64 which should not have this problem.
Also move the FIXME to the correct place.
Also add some minimum comments about this...
