[EABI] Add Clang support for -meabi flag The -meabi flag to control LLVM EABI version. Without '-meabi' or with '-meabi default' imply LLVM triple default. With '-meabi gnu' sets EABI GNU. With '-meabi 4' or '-meabi 5' set EABI version 4 and 5 respectively. A similar patch was introduced in LLVM. Patch by Vinicius Tinti. llvm-svn: 252463
