[bug#49025] [PATCH v3 core-updates 33/37] tk: Do not use %build-inputs when cross-compiling.

[Maxime Devos]

%build-inputs does not exists when cross-compiling,
so use #$(this-package-input ...) instead.

* gnu/packages/tcl.scm
  (tk)[arguments]<#:configure-flags>: Use 'this-package-input'
  instead of '%build-inputs' when cross-compiling.
