[PATCH] D31603: [ELF] Fail the link early if a map file path is invalid

[James Henderson via Phabricator via llvm-commits]

jhenderson created this revision.

As with the changes made in https://reviews.llvm.org/rL297645, we do not want a potentially long link to be run, if it will ultimately fail because the map file is not writable. This change reuses the same functionality as the output file path check. See https://reviews.llvm.org/D30449 for further justification and explanations.
