Picture evidence that this PR prints out the linker arguments in that failure case. |

There was a problem hiding this comment.
Can this change be saved for later? Papering over this unfortunately probably won't fix much, the syntax for calling lib is very different than ar, so this will never work if it's actually used. This should basically just return an option and then it's handled elsewhere when it's not available

It fixes the sanity check. In all cases where cc2ar is called or the .ar() of the Build is called, the result is never used on msvc, except for the sanity check. But I'll move it to a separate PR and do the Option thing.

Attempt to diagnose #33844 #33844 is a spurious failure that causes builds to fail due to the linker command sometimes failing with error 206, which means that the command is too long. This PR makes rustc print out the linker arguments in that case so the reason for it being so long can be diagnosed and hopefully fixed. r? @alexcrichton
