[pkg-gnupg-maint] Bug#911377: libgpg-error: building architecture-independent-only packages fails with "libgpg-error-l10n missing files: usr/share/locale'

[Daniel Kahn Gillmor]

Source: libgpg-error
Version: 1.32-2
Severity: normal
Control: tags -1 + help confirmed

when trying to build from source with "gbp buildpackage -A" or
"dpkg-buildpackage -A", the build fails, terminating the following
error message:

This doesn't seem to be a problem on the debian build daemons, because
the arch:all builder apparently also builds arch-dependent packages,
which lets the necessary files get created correctly before the
installation.

So i don't think this is a high priority, but it seems like it
*should* work, and we should be able to generate the libgpg-error-l10n
package OK.

some possible options i've thought of (but haven't tested):

 a) have the arch-independent builds actually kick off the
    arch-dependent packages as well, just to populate the files

 b) install the l10n files from one of the mingw builds instead of the
    stock installation.

I welcome well-tested patches that would resolve this and look
reasonable at the same time :)
