No, the opposite. We need to autoreconf to be able to patch our the 'ln
--relative' calls. And to be able to autoreconf, we need this
libgcrypt.m4 stuff.

To me, hacking around the 'ln --relative' problem is not a proper
solution. Because the next time we need a patch for systemd that
requires autoreconf (like if we backport a fix from upstream or another
change), then we will be back to the current situation where autoreconf
cannot be done with libgcrypt.m4.

So I agree with the solution proposed by Eric here to bundle the
libgcrypt.m4 file.

Best regards,

Thomas
