All qttools are not getting built for target architecture when cross compiling

I am cross-compiling Qt 5.15.8 on an Apple M1 machine to target arch x86_64 using the following configure command

../configure $OPTIONS -device-option QMAKE_APPLE_DEVICE_ARCHS="x86_64" 

The frameworks are all built for x86_64 but only some tools in the bin directory are getting built for x86_64 (eg qtdbus, macdeployqt).

If I omit the -device-option flag and run the following configure command, then everything except qmake gets built for x86_64.

../configure $OPTIONS QMAKE_APPLE_DEVICE_ARCHS="x86_64" 

Is it incorrect to use the -device-option flag here and is it possible to build qmake as well for x86_64?
