clang-9.0 @9.0.1_4: dependency cycle on Snow Leopard (clang-9.0 -> llvm-9.0 -> python27 -> openssl -> clang-9.0)

Description
It is currently impossible to install clang-9.0 on Snow Leopard, seemingly due to a dependency cycle with openssl:
$ sudo port install clang-9.0 ---> Computing dependencies for clang-9.0 The following dependencies will be installed: clang-9.0 llvm-9.0 openssl python27 xar Continue? [Y/n]: Error: The following dependencies were not installed because all of them have unmet dependencies (likely due to a dependency cycle): llvm-9.0 python27 openssl clang-9.0 xar Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug. Error: Processing of port clang-9.0 failed
openssl is pulled in as a dependency to python27:
$ port rdeps clang-9.0 The following ports are dependencies of clang-9.0 @9.0.1_4+defaultlibcxx+emulated_tls+libstdcxx: xz clang-3.4 cctools libunwind-headers xz-bootstrap llvm-3.4 libffi expect automake autoconf gettext libiconv gperf libcxx ncurses m4 clang-3.7 llvm-3.7 libedit zlib python27 pkgconfig bzip2 db48 expat openssl clang-9.0 cmake curl libidn2 libunistring perl5 perl5.28 gdbm readline texinfo help2man perl5.30 p5.30-locale-gettext libtool xattr unzip libpsl python39 sqlite3 python_select python3_select zstd lz4 curl-ca-bundle libarchive libxml2 icu lzo2 libuv legacy-support libomp llvm-9.0 xar llvm_select clang_select ld64 ld64-127 libmacho-headers openssl11 python2_select tcl dejagnu ncurses-bootstrap python27-bootstrap pkgconfig-bootstrap libiconv-bootstrap gperf-bootstrap gettext-bootstrap
This is a fresh MacPorts installation on Mac OS X 10.6.8, it appears the issue can also be currently seen on the openssl Snow Leopard automatic build #75127: https://build.macports.org/builders/ports-10.6_x86_64-builder/builds/75127.

Can you explain how the PR has changed the compiler selection, as I don't see it ?

By removing the part with the comment
# Having the stdlib set to libc++ on 10.6 causes a dependency on a # macports-clang compiler to be added, which would be a dep cycle.
Just clear compiler.cxx_standard since openssl is all C anyway.

the openssl
port doesn't build anything at all, it just creates sym links. Anyway I have pushed that change in https://github.com/macports/macports-ports/commit/22aae98bd2b8b72f7e10f7bec302f3af257fe98b

https://github.com/macports/macports-ports/pull/12514 appears to have changed openssl's compiler selection for 10.6.
