[musl] Default binding directory for gettext

["A. Wilcox" <AWilcox@Wilcox-Tech.com>]

Hi,

While updating the package ‘cracklib’ for Adélie Linux, I found it does
not give localised messages, because it does not call bindtextdomain(3),
only textdomain(3).  This does work on glibc and GNU gettext as a
library, which use /usr/share/locale as a default binding.

Is it intentional that there is no default binding for gettext?  I
believe the GNU implementation is meant to be canonical for behaviour of
gettext, and this seems to not match.  From
https://www.gnu.org/software/gettext/manual/html_node/Locating-Catalogs.html,
emphasis mine:

> The directory name given in bindtextdomains second argument **(or the
default directory)**, followed by the name of the locale, the locale
category, and the domain name are concatenated

Since this technically isn’t portable when the software is installed in
a different $PREFIX, I did open
https://github.com/cracklib/cracklib/pull/50, so this should be fixed in
a future release of the package.  Still, I wasn’t sure if this musl
behaviour was desired or not.  My personal feeling is that both are
wrong; bindtextdomain is needed in the case of non-standard PREFIX, but
musl should have a default fallback path for packages that elide the
call.

Best,
-A.
