[Buildroot] [PATCH] pacakge/qt5/qt5base: fix build with ccache

Building with ccache failed with:
Running configuration tests...
Failed to process makespec for platform 'devices/linux-buildroot-g++'
Project ERROR: Compiler <path_to_output_dir>/host/usr/bin/ccache <path_to_output_dir>/host/usr/bin/<cross_compile>-g++ not found. Check the value of CROSS_COMPILE -device-option
Could not read qmake configuration file <path_to_output_dir>/build/qt5base-5.5.0/mkspecs/devices/linux-buildroot-g++/qmake.conf.
Error processing project file: /dev/null
This was caused by Buildroot setting this in
qt5base-5.5.0/mkspecs/devices/linux-buildroot-g++/qmake.conf:
QMAKE_CXX = $${BR_CCACHE} $${CROSS_COMPILE}g++
But qt5base-5.5.0/mkspecs/features/device_config.prf expects QMAKE_CXX
to be a valid (absolute or QMAKE_PATH_ENV-relative) path to an existing
file, which is not possible if using ccache as above.
Add a patch removing these tests since the toolchain is already tested
by Buildroot, which allows to keep using ccache.
