tar-replacement-native: Add a target to replace the default tar

tar < 1.24 has symlink issues where extracting a tar archive containing a symlink
to a directory where that symlink already exists will cause the symlink to be
dereferenced. If that target doesn't exist tar can fail with a permissions error.

Since we need to be able to do this for packages containing symlinks like
xorg-minimal-fonts and eglibc, we have to ensure a tar 1.25 is available early
in the build process.
