Dimitry Andric 07b202a847 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to ... get rid of testing explicitly for clang (using ${CC:T:Mclang}) in individual Makefiles. Instead, use the following extra macros, for use with clang: - NO_WERROR.clang (disables -Werror) - NO_WCAST_ALIGN.clang (disables -Wcast-align) - NO_WFORMAT.clang (disables -Wformat and friends) - CLANG_NO_IAS (disables integrated assembler) - CLANG_OPT_SMALL (adds flags for extra small size optimizations) As a side effect, this enables setting CC/CXX/CPP in src.conf instead of make.conf! For clang, use the following: CC=clang CXX=clang++ CPP=clang-cpp MFC after: 2 weeks		2012-02-28 18:30:18 +00:00
