Hello Yegor,

Sorry for the long delay before reviewing this. I believe it's almost
ready, just a couple of comments below.

From my testing you also need:

	depends on !BR2_PREFER_STATIC_LIB

because zlog only produces a shared library.

This needs to be updated to take into account the !static lib
dependency.

The license is LGPLv2.1.

Why do you pass INCLUDE_PATH=include and LIBRARY_PATH=lib ? Looking at
the makefile of zlog, these seem to be the default values.

Thanks!
