We need to disable any systemd parts using either IDN or NSS.
IDN is only disabled in C library function call to getnaminfo(),
it does not effect libidn/libidn2 usage in systemd.
Tested with qemu-system-arm.

v1 -> v2:
- added Upstream commit URL suggested by Thomas Petazzoni
- rework enable/disable options suggested by Thomas Petazzoni
- extend commit message a little bit
v2 -> v3:
- sync to latest master changes
- remove patches included upstream
- disable features not usable with uClibc-ng lacking nss.h

Hi Waldemar,
If you're willing to go through another round, I have a few remarks...

Could you add a comment why this doesn't work on uClibc?
Normally for packages that have a library dependency we add a comment line. I'm
not sure if we really want that here, though, it's making things a little heavy
maybe. Although, in the menu it would look pretty OK I think. What do you think?
Both comments repeated for the rest of this file.

^^^^^ or uClibc? :-)

Maybe add parenthesis here for clarity - I'm not sure what the binding is of ||
and && in kconfig...
Regards,
Arnout

I will do, but want to wait for the defconfig from Thomas to
see if I can fix his issues before respinning. It is to late
for this release anyway.
best regards
Waldemar
