chromium: [PATCH] build/config/compiler/BUILD.gn: Disable CREL

This feature is not supported on the current clang toolchain version,
which causes build to fail with the following error:

| clang++: error: unsupported argument '--crel' to option '-Wa,'
| clang++: error: unsupported argument '--allow-experimental-crel'
  to option '-Wa,'
