Comment (by JDLH):

 This fix, to cross-build as x86_64 on arm64, caused MacPorts to reinstall
 all '''qt4-mac''' dependencies as `+universal` variants, on my arm64-based
 MacBook Pro running macOS Monterey version 12.3.1. This it turn triggered
 #64933, where destroot fails on arm64 for port '''tiff +universal'''. I
 point this out, in case others encounter the same problem. It does not
 invalidate this fix.

 My workaround was to abandon my attempt to install '''qt4-mac'''. As
 pointed out here, it is old code. MacPorts has support for Qt5 and Qt6.
 And, once all dependencies install successfully as `+universal` variants,
 I suppose '''qt4-mac''' as x86_64 will be usable on arm64 also, via
 Rosetta 2.
