ccache: Fix for distcc cross-compiling / various improvements (#1026)
* ccache: Fix for distcc cross-compiling / various improvements * Make ccache work when cross-compiling with distcc (fix #716) * Allow to configure the ccache size in "pmbootstrap init" * Moved ccache stats code from pmb/build/other.py to pmb/helpers/frontend.py * Grouped job count, ccache size and timestamp based rebuilds together to "build options" and allow to skip them * Sorted config options that had to be modified anyway alphabetically * Improve comment in arch-bin-masquerade APKBUILD
