Then we should fix BR2_PACKAGE_ELFUTILS_PROGS, BR2_PACKAGE_MONGREL2,
BR2_PACKAGE_NSS_MDNS and BR2_PACKAGE_TZDATA (even though for the
latter, I'm not sure, since tzdata is not useful at all with uClibc).

Right.

Correct. I've mainly taken Henk's patch and tried to make it suitable
for upstream. Further improvements are definitely needed.

As far as I can see, it doesn't have any build-time dependency. It's
just a bunch of pre-built shared libraries and header files that get
copied around. At runtime, I believe a specific kernel driver is
needed.

But Arnout/Henk can probably comment on this.

Thanks,

Thomas
