OK, so I finally had the time to give it a shot:

  - the autoreconf issue is because it uses pkg-config macros, and it
    was missing a dependency on host-pkgconf,

  - the build issue is because a pure static uClibc build does not
    install dlfcn.h and can't do dynamic loading with dlopen().

Both issues already existed with the previous version, we just did not
notice them...

So: thanks for noticing this time! ;-)

I'll send the patches in a moment.

Regards,
Yann E. MORIN.
