Run 'pmbootstrap aportgen gcc6-aarch64 gcc6-armhf' again and commit
the resulting changes, as these packages are meant to be always
auto-generated and therefore in sync with main/gcc6.
This changes the pkgver to 9999, as it was required in main/gcc6 to
avoid conflicts with Alpine's gcc6 package.
This covers most use cases and saves a lot of build time. Can be
changed on demand. Again, this simplifies package building as part of
the new build infrastructure effort. [skip ci]
I thought only having specific symlinks was enough, and it was for one
kernel. However, to make sure it works with all kernels, let's just add
symlinks for all the binutils.
