[Buildroot] [PATCH v2] qt5base: use ccache if enabled

[Fatih Aşıcı]

For now, it doesn't use ccache when compiling host tools (e.g. qmake).
It seems the fix is not trivial.

Changes v1 -> v2:
  - pass ccache path to CROSS_COMPILE instead of setting another device
    variable (suggested by Peter Korsgaard)
