Fix flags for annobin in Qt tools build

Generate Makefiles of Qt tools (bat, tray-monitor) before the build in
order to pick up the right compiler/linker flags.

Regenerate the Makefiles again after the build to have the correct
install targets. Not sure why the regeneration before build results in
incorrect install target in Makefiles, but this workaround is confirmed
to work.

Remove the second %make_build in tray-monitor, the tool has been built
already, so this has no effect.
