If you really want to be pedantic, you could write:

	depends on !BR2_NEEDS_GETTEXT || BR2_USE_WCHAR

but it anyway makes the Config.in comment handling a bit annoying. And
it's in fact a bit useless:

 - On glibc, BR2_USE_WCHAR is always 'y', and BR2_NEEDS_GETTEXT is false

 - On musl, BR2_USE_WCHAR is always 'y', and BR2_NEEDS_GETTEXT is false

 - On uClibc, BR2_NEEDS_GETTEXT is 'y', and indeed BR2_USE_WCHAR needs
   to be set.

So in fact, a "depends on BR2_USE_WCHAR" is good enough.

Thanks!
