Create symlinks for all supported arches (armhf, armv7, aarch64, x86_64,
x86), not only armhf and aarch64. Skip creating symlinks for the arch
that the package gets built for, so we can include x86_64 in the list
without conflicting with the ccache package from Alpine.
Link to ../../../bin/ccache instead of /usr/bin/ccache, so it works
properly with crossdirect (where we mount the native chroot to /native
in the foreign chroot).
Add symlinks for clang and clang++.
* 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
