Hi all,

Some python packages (e.g. soundfile) rely on find_library (from
ctypes.util) to resolve the name of a dynamic library at runtime in a
platform-independent way.

On Linux, the implementation of find_library [1] requires one of the
following:
 - ldconfig
 - gcc + objdump
 - ld + objdump

Neither of the above make much sense on an embedded target. Does anyone
have advice or recommendations on how to deal with such packages, short of
just patching the sources to avoid the use of find_library?

Thanks,
