if libcommuni is patched for QT6 support, spectrum2 will fail to compile

[dekeonus]

Gentoo has removed qt5 libraries, as part of doing so they have patched libcommuni to support QT6.

spectrum2 will fail to compile with libcommuni patched linked against QT6

[dekeonus]

I should have been clearer: libcommuni-6.7.0 has qt6 support, but is missing some imports for core5compat (see communi/libcommuni#116 )¹ and uses removed (long depreciated) QAbstractSocket::error(QAbstractSocket::SocketError socketError) signal (see communi/libcommuni#115 )²

² This PR is not included with gentoo's build - but I've opened a bug on gentoo's bugzilla for it

libcommuni is dead, and it's no longer worth supporting. These days, you can one-shot an IRC library with an LLM.
