devel/android-tools-simpleperf fails to build with llvm10

[Matthias Apitz]

Hello,

On head with ports of head to the port devel/android-tools-simpleperf
fails to build with the error:

...
--- read_elf.o ---
In file included from read_elf.cpp:34:
In file included from /usr/local/llvm10/include/llvm/ADT/StringRef.h:12:
/usr/local/llvm10/include/llvm/ADT/STLExtras.h:559:49: error: no template named 'index_sequence' in namespace 'std'
  template <size_t... Ns> value_type deref(std::index_sequence<Ns...>) const {
                                           ~~~~~^

  decltype(iterators) tup_inc(std::index_sequence<Ns...>) const {
                              ~~~~~^
...

Maybe it's related to make.conf(5) setting:

DEFAULT_VERSIONS+=llvm=10

I could post the complete poudriere build log if necessary.

Thanks
