This is because HAVE_DLFCN_H is not set because dlfcn.h is not provided by the toolchain. But ./os/unix/dlib.c uses dlopen and dlclose functions.
Apparently, this is missing on uClibc when it is configured as a static-only C library.

What would be the best way to fix it? Maybe a "depends on !BR2_STATIC_LIBS" ?
