When host-gettext is built, then we could use it, otherwise target wine will be english only.
I don't think this diserves a hard dependency, do you?

Wine has a tool called wrc which transforms dialogs/strings and such into a windows like resource file.
With the help of the gettext library wrc merges the translations from wines po-files into that resource file.
As the wrc tool from host-wine is used, we need the gettext support there.
Further there are no runtime requirements, so in fact it doesn't matter to wine(or even host-wine) if the target
gettext is built.
Note: host-gettext and target gettext are two different things:

# For the target version, we only need the runtime, and for the host
# version, we only need the tools.
GETTEXT_SUBDIR = gettext-runtime
HOST_GETTEXT_SUBDIR = gettext-tools
