Thomas, All,

Is that fixed in Buildroot with that patch patch:
    package/uclibc/0.9.33.2/0062-nptl-remove-duplicate-vfork-in-libpthread.patch

It is not in upstream uClibc yet, so I've pinged them about applying
that patch.

I'm a bit warry of carrying patches in crosstool-NG, that are not
upstream. But uClibc is, well, a special case, isn't it? ;-)
Maybe I could just vampirise the patches from Buildroot, and be done
with it.

O...K... Well, fdt support comes later in my series, and it is a part
that is not yet applied.

I'll see to re-order the series to be able to just submit the FDT part,
before the release.
