            Bug ID: 226684
           Summary: Unexport llvm coverage symbols to fix build
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Unexport llvm coverage symbols to fix build

Even after the fix in r278444 for Bug 226562, some internal projects still failed to build during the GenerateTAPI build phase:

    error: headers don't have symbol '(weak-def) ___llvm_profile_filename'
    error: headers don't have symbol '(weak-def) ___llvm_profile_raw_version'
    error: headers don't have symbol '(weak-def) _lprofDirMode'

So instead of just ignoring these weak external symbols in check-for-weak-vtables-and-externals, we need to unexport them.
