package/qt5/qt5base: use ccache for building host code
qt5 currently doesn't use HOSTCC/HOSTCXX, so it doesn't use ccache
when building all its host code (especially qmake). This means that
even with ccache enabled and a hot cache, it still takes a long time
to build qt5base.
Before this patch, building qt5base takes:
- 446 seconds with a cold ccache
- 185 seconds with a hot ccache
This is because the ccache is not used for host code.
After this patch, building qt5base takes:
- 450 seconds with a cold ccache
- 15 seconds with a hot ccache
