Refactor llvm_config.mk and support the 2nd arch 1. Following the setup of gcc in build/core/combo/, we added the [HOST\|TARGET]_<arch>.mk clang config files, and load only the configs needed by the current product. 2. Added support for the 2nd arch.

[MIPS] Temporarily disable Mips shared-textrel errors Clang++ for Mips and Mips64 generates read-only exception unwind tables that trigger DT_TEXTREL warnings at link time. Until Clang is fixed, ignore those performance warnings instead of failing the build. With this patch, Mips clang++ can be (optionally) used when building libdeqp. NDK's Mips llvm has been using an alternate temporary fix, marking the .gcc_exception_table section as read-write for Mips only: https://android-review.googlesource.com/#/c/119660/ A permanent fix using a read-only exception table is pending upstream: http://reviews.llvm.org/D9669 Change-Id: Ie0cd7da398acbe45dbe39adc251e7fd5b5ca1445 2015-04-30 01:20:51 +02:00			`# Temporary workaround for Mips clang++ problem, creates`
