Please review this PR that fixes JDK build configure failure when using clang after JDK-8338304:
Found candidate GCC installation: <snip> Selected GCC installation: <snip> ... clang: error: unsupported option '-V -static-libgcc' configure:85215: $? = 1 configure:85204: <snip> -qversion >&5 clang: error: unknown argument '-qversion'; did you mean '--version'? ... Tool from Clang GCC installation is being picked up unexpectedly (JDK build configured with `--with-toolchain-type=clang`). With this fix, it avoids `UTIL_REQUIRE_PROGS(LLD, lld)` if user supplies compiler toolchain. The user supplied compiler toolchain is used by setting `CXX=<user_specified_path_to_tools_script>` during configuration. ------------- Commit messages: - Don't do UTIL_REQUIRE_PROGS(LLD, lld) if user supplies compiler name.
