Subject: Re: [PATCH] BaseTools/tools_def: add CLANG38 LTO versions for AARCH64 and ARM

Hi Ard,
I'm OK for the patch.
BTW, would you mind to help add the "-Wno-unused-const-variable" in the CLANG38_WARNING_OVERRIDES? I happen to need add it in CLANG38 (https://bugzilla.tianocore.org/show_bug.cgi?id=790) and I see it seems a shared flag for ARM/AARCH64 as well.
