Subject: [PATCH] CMake: Rename xz and man page symlink custom targets.

The Ninja Generator for CMake cannot have a custom target and its
BYPRODUCTS have the same name. This has prevented Ninja builds on
Unix-like systems since the xz symlinks were introduced in
80a1a8bb838842a2be343bd88ad1462c21c5e2c9.
