build, qt: Native Qt builds in depends do not work #21588
Description
macOS
When doing % make -C depends qt_configured the native build is expected:

Actually, a cross-compile build is configured:

The reason for this behavior is the line which was added in #21376:
bitcoin/depends/packages/qt.mk
Line 116 in e08f319
-device-option is a cross-compile option, and it triggers cross-compiling.
It is worth to mention that before #21376 native builds with depends on macOS were broken (#14648, #19785).
Linux x86
Again, no native build when it is expected:
$ make -C depends qt_configured

This should fix the gitian build issue
ARM
Just broken.
