Description of the problem / feature request:

In some cases, clang outputs absolute paths to the dot-d files for objective-c source files. The bazel5 code that detects inclusion problems with Objective-C source files fails.

Feature requests: what underlying problem are you trying to solve with this feature?

One of my objective-c libraries has source files whose corresponding .d files contain absolute paths.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

1. Clone and check out the rules_ios WIP PR here: Repro problem with absolute paths in dot-d files breaking inclusion validation in bazel5 bazel-ios/rules_ios#366
2. Run bazel build -s //tests/ios/InclusionProblemRepro:LibraryA_objc

Expected result: build succeeds
Actual: Build fails with the error message: ERROR: /Users/amberdixon/Development/rules_ios/tests/ios/InclusionProblemRepro/BUILD.bazel:3:14: Compiling tests/ios/InclusionProblemRepro/Classes/Extensions/D.m failed: undeclared inclusion(s) in rule '//tests/ios/InclusionProblemRepro:LibraryA_objc': this rule is missing dependency declarations for the following files included by 'tests/ios/InclusionProblemRepro/Classes/Extensions/D.m': '/private/var/tmp/_bazel_amberdixon/bee3f665d317c886aa3a5be8caf5517a/sandbox/darwin-sandbox/12/execroot/build_bazel_rules_ios/tests/ios/InclusionProblemRepro/Classes/HeaderB.h' Target //tests/ios/InclusionProblemRepro:LibraryA_objc failed to build

Also note that the .d file for this source has an absolute path:

What operating system are you running Bazel on?

MacOS 11.6.1

What's the output of bazel info release?

development version

If bazel info release returns "development version" or "(@Non-Git)", tell us how you built Bazel.

Cherry-pick this commit (d966a0d) onto the 5.0.0-pre.20211011.2 bazel pre-release and rebuild bazel.
