They have different build directories:
 ls lib/builtins/CMakeFiles                                                                                                         \
        clang_rt.builtins-arm.dir  clang_rt.builtins-armv6m.dir
and separate output files:
 ls lib/linux/libclang_rt.builtins-arm*.a                                                                                           
        lib/linux/libclang_rt.builtins-arm.a  lib/linux/libclang_rt.builtins-armv6m.a
