- consistent platform detection in all methods from setup.py;
- readline libraries detected by configure script are used for setup.py : this could help to detect is more platform independent way if readline is linked with ncurses{w} library;
- ignore "friendly" search library paths : this is useless in case of cross-compilation . Also it is reported that those paths are not so "friendly" even in native builds. Note that with "friendly search library paths" python library search based on file suffix will find libraries system on build system if host system lack them.
