[bitbake-devel] [PATCH 2/2] bb/utils: fix contains_any()

[Ross Burton]

"set1 in set2" doesn't do what you'd expect, and if it did do a subset test
that's not the logic required by contains_any().

Instead get the intersection of checkvalues and val and check if the resulting
set is empty or not (by evaluating it in a boolean context), which tells us if
there are any elements in common.

Based on a patch by Valentin Popa <valentin.popa at intel.com>.
