In https://bugzilla.tianocore.org/show_bug.cgi?id=2842 clang support was added by having users specify "make CXX=llvm" when building BaseTools. The Makefile then sees that and sets CC=$(CLANG_BIN)clang and CXX=$(CLANG_BIN)clang++. That requires that the executables 'clang' and 'clang++' exist and for example aren't named 'clang-17' and 'clang++-17'. Also, it's an unusual way of specifying the compiler, since many users will expect to be able to override CC and CXX on the make command line. Rework the BaseTools Makefiles removing the 'BUILD_' prefix (BUILD_CC and BUILD_CXX) and using the standard name 'LDFLAGS' instead of 'LFLAGS'. This allows clang to be used by running 'make -C BaseTools CC=clang CXX=clang++'. Signed-off-by: Rebecca Cran <rebecca@quicinc.com> Reviewed-by: Liming Gao <gaoliming@byosoft.com.cn>
