[OE-core] libs transition /usr/lib -> /lib questions

[Andreas Müller]

Hi

currently some libs are moving from $libdir (/usr/lib) -> $base_libdir (/lib). I 
have the following questions:

* can sombody explain a bit more what is it for and how the decision is made to 
transit libs? I read the commit messages but still have no idea what this 
enhances / fixes. What is 'not safe' or - I guess the insane.bbclass modification 
deals same issue - 'system recovery'. Is that something I (should) have? :)
* can somebody please take care what I see with meta-oe / obexd:

libusb-1.0.la still resides in .../sysroots/overo/usr/lib. Maybe it needs 
transition too? If yes: Are there also others which need libtool-lib transition?

Thanks
