[PATCH] D36029: [sanitizer_common] Disable filesystem-related code for Fuchsia

[Roland McGrath via Phabricator via llvm-commits]

mcgrathr created this revision.
mcgrathr added a project: Sanitizers.
Herald added a subscriber: kubamracek.

Fuchsia doesn't support filesystem access per se at low level.
So it won't use any of the filesystem-oriented code in sanitizer_common.
