Bug 139609 – [Mac] Work around a bug in dsymutil on older OS versions

• Status: RESOLVED
• Resolution: FIXED
• Component: WebCore Misc.

[Mark Rowe (bdash)]

The version of dsymutil that's part of the toolchain on older OS versions has a bug that limits the size of each architecture's slice of the dSYM file to 2GB (<rdar://problem/16045763>). WebCore is now exceeding that size, which causes dsymutil to fail to generate a dSYM bundle for WebCore, resulting in a build failure.

I'm not sure if this will work to override CLANG_DEBUG_INFORMATION_LEVEL from Base.xcconfig because the [sdk=] selector is more specific than this declaration.

I tested it on OS X 10.9 and 10.10 and it gave the expected results. Which configuration do we expect to give the wrong outcome?

EWS bots are running 10.8, so probably that one.  :|

Oh, maybe this only happens when using $(inherited).  The issue I saw was with OTHER_LDFLAGS.
