[Buildroot] [PATCH 16/23] qt: disable precompiled headers when ccache is enabled

ccache and precompiled headers don't work together, so disable
precompiled headers when ccache is enabled.

The benefit of ccache compiling Qt a second or more time is much
higher than the costs of disabled precompiled headers in the first run.
