I dug for it (libcap) since I couldn't find any reference in wscript & co and finally a 
$ for l in tmp/sysroots/curie/usr/lib/lib*.so; do tmp/sysroots/x86_64-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/4.9.3/arm-poky-linux-gnueabi-objdump -x $l; done | less
pointed the origins:

* libldap_r.so
* libsmbconf.so

Think it shouldn't be a dependency in tevent, but in openldap ...

I add it to my patch series - just wanted to let you know.

Wrt. libbsd - if libbsd is found, stdlcat etc. is used from there, otherwise own implementation via lib/replace is provided, similar for some attr calls - but they aren't used in tevent/talloc ...
Looks as if lib/replace is a poor maintained libnbcompat alike :)

Cheers
