[cfe-dev] Add -fno-plt,-fplt to ignored flags

[Jordan Glover via cfe-dev]

Thanks for the reply.
-fno-plt flag is going to be used as default build flag for every package available in Archlinux [1]. There were concerns about that change breaking clang but it was decided to add patch similar as mine [2]. Also some developers advised to submit such patch upstream [3][4].
