Allow passing RTLIB=compiler-rt to make

justinkb · vondele · commit 516ad1c9bf7d · 2021-07-03T09:51:03.000+02:00
Not all linux users will have libatomic installed. When using clang as the system compiler with compiler-rt as the default runtime library instead of libgcc, atomic builtins may be provided by compiler-rt. This change allows such users to pass RTLIB=compiler-rt to make sure the build doesn't error out on the missing (unnecessary) libatomic. closes #3597 No functional change
