[Buildroot] [PATCH v1] package/webkitgtk: disable internal ccache configuration

[Thomas Devoogdt]

From: Thomas Devoogdt <thomas.devoogdt at barco.com>

WebKit's auto-configured ccache results in 100% cache misses.
Disable WebKit's internal ccache setup [1] since Buildroot
already manages the ccache in toolchain/toolchain-wrapper.c.
