configure: not canonicalizing relative directories

[Ionic]

A call like ./configure [...] --local-rust-root=./build/stage0 (possibly also --llvm-root and others) will lead to very difficult-to-debug errors.

I spent two hours trying to figure out why bootstrapping core always failed with an OS error ("No such file or directory"). It boiled down to the bootstrap compiler not being executable since configure does not canonicalize relative paths.

@Ionic are you still running into this problem? If so, can you give a full set of commands to reproduce the error? I ran this locally and it seemed to work ok.

I can't tell or test right away. :/

I haven't touched the OS X machine I've been seeing this error with for two years. Note that the issue is four years old by now. Might have been fixed by now. Maybe we can close the report for now and I can re-open it (or add another comment?) if I still see it?

👍 sounds good, I appreciate the quick response.
