Hi!

On m68k, the build currently fails with ccache enabled due to a bug in qemu-user:

FAILED: Source/JavaScriptCore/CMakeFiles/JavaScriptCore.dir/heap/StructureAlignedMemoryAllocator.cpp.o 
/usr/bin/ccache /usr/bin/c++ -DBUILDING_GTK__=1 -DBUILDING_JavaScriptCore -DBUILDING_WITH_CMAKE=1 \
(...)
-o Source/JavaScriptCore/CMakeFiles/JavaScriptCore.dir/heap/StructureAlignedMemoryAllocator.cpp.o \
-c /<<PKGBUILDDIR>>/Source/JavaScriptCore/heap/StructureAlignedMemoryAllocator.cpp
ccache: pthread_mutex_lock.c:94: ___pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed.
qemu: uncaught target signal 6 (Aborted) - core dumped
Aborted

This issue can be worked around by disabling ccache which will prolong the build times, of course, but
at least the package gets built.

Thus, could you disable ccache on m68k with the following change to debian/control{,.in}:
