Subject: [PATCH] The change in r90189 adds a link in a directory outside the
 iPhone platform directory when building the llvmCore_Embedded project.  Fix
 this by putting the iPhone platform directory into DEST_DIR instead of
 DEST_ROOT.  I also noticed what appears to be an unintentional use of
 DEVELOPER_BIN instead of DEVELOPER_DIR, so I fixed that and changed to use
 DEVELOPER_DIR in some places that were hardcoded to "Developer".  Finally,
 the other changes here allowed some refactoring and simplification, which I
 have done.
