macos: qt6-qtbase build broken

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I'd like to install wireshark on macOS from pkgsrc, but there is no
binary package available. Looking at the latest macOS bulk report,
this happens because qt6-qtbase does not build on macOS, with:

https://us-central.manta.mnx.io/pkgsrc/public/reports/Darwin/11.3/arm64/20230925.2131/qt6-qtbase-6.5.2nb1/configure.log

...
Support enabled for:
  Using pkg-config ....................... yes
  udev ................................... no
  OpenSSL ................................ yes
    Qt directly linked to OpenSSL ........ no
  OpenSSL 1.1 ............................ yes
  OpenSSL 3.0 ............................ no
  Using system zlib ...................... yes
  Zstandard support ...................... yes
  Thread support ......................... yes
...
ERROR: Feature "openssl": Forcing to "ON" breaks its condition:
    QT_FEATURE_openssl_runtime OR QT_FEATURE_openssl_linked
Condition values dump:
    QT_FEATURE_openssl_runtime = "OFF"
    QT_FEATURE_openssl_linked = "OFF"


Does anyone know what it wants to tell us, and how to fix that?

Thanks,
 Thomas
