* gnu/packages/groff.scm (groff)[arguments]: Replace build phase to pass
GROFF_BIN_PATH and GROFFBIN variables when cross-compiling.

Also add native groff as an input.

You’d need to mention ‘self-native-input?’ explicitly.

However, this field no longer exists: see commit
a7646bc5e17a829d23519d0b199a576fb1edbd04, and see
528ea990c3a815cb4b0ded913ea22cdc778839bd for how to adjust your package.

If you make it conditional on (%current-target-system) , that’ll avoid a
massive rebuild of the 4K packages that depend on ‘groff’, and thus
it’ll be applicable on ‘master’.

Could you send an updated patch?

Thanks,
Ludo’.
