Right.
> Does the target Qt also have a qmake, moc and uic ?
No, there is no need for them.
They aren't supposed to be run on target machine.
Also, there is no reason of running them on host either.
But again, other cross-environments may have them.

In general, no.
Any such relation is either quite cross-environment specific or non-existent.
For example,
1) moc and uic are located at /home/me/cross-devel/tools/bin
2) target lib dir is /home/me/cross-devel/build/my_internal_target_name/usr/lib
That is why, I do like the idea of using pkg-config:
1) .pc files are usually placed near libraries (${libexecdir}/pkgconfig)
2) It's easy to tell pkg-config the sysroot dir
