[bug#49025] [[PATCH v2 core-updates] 07/37] tzdata: Don't bother with cross-compiling.

[Maxime Devos]

The time zone database is architecture-independent,
so trying to cross-compile it is pointless!

* gnu/packages/base.scm
  (tzdata)[arguments]<#:target>: Set to #f.
  (tzdata)[allowed-references]: Only include the "out" output itself,
  to make sure no (architecture-dependent) binaries are installed.
