Hi Thomas,

A bit late - was on FTO in the end of last week.

I already commented on that one.
Basically gnuradio includes source from boost and in boost itself they
use syscall directly if (__GLIBC__ == 2 && __GLIBC_MINOR__ < 8) which
is the case for uClibc, see http://git.uclibc.org/uClibc/tree/include/features.h#n395
-------------->8--------------
#define	__GLIBC__	2
#define	__GLIBC_MINOR__	2
-------------->8--------------

From Boost standpoint this looks like some sort of backward compatibility for older
glibc that didn;'t have eventfd() defined.

So probably  the best option here is to bump __GLIBC__/__GLIBC_MINOR__ in uClibc.
Maybe Waldemar may comment on that?

Libsodium attempts to build as PIE.
Should be fixed by http://patchwork.ozlabs.org/patch/505568/
