rpi2_avahi_dbus_libglib2_defconfig

When compiling the avahi package in both buildroot 2016.08 and master (from Today), I get the following error message:
------8<------8<------8<------8<------8<------8<------
Making all in avahi-utils

------8<------8<------8<------8<------8<------8<------

To reproduce this bug, start from the defconfig for RPI 2 (raspberrypi2_defconfig), then select dbus, libglib2, avahi, and avahi-daemon (or use the attached defconfig).

Note, a workaround is to also select BR2_TOOLCHAIN_BUILDROOT_LOCALE. So, avahi.mk adds libintl since BR2_NEEDS_GETTEXT_IF_LOCALE is defined.

I don't know how to solve this issue properly.

I may have a solution (see attached patch).
It does fix the compilation error in my case but I'm not sure it doesn't compile with libintl too often.
Comment 2 Thomas Petazzoni 2017-07-15 09:33:58 UTC 
I believe this issue has been resolved by the recent gettext reworked, merged in master since early July. Now, all 3 C libraries have a gettext implementation built-in, which allows to avoid a lot of those issues.
