[OE-core] Lots of [host-user-contaminated] warning

[Andreas Müller]

Hi,

this bugs me for a while and I wonder if I am again the only one
facing this: I get floods of warnings for sourcecode files as

WARNING: QA Issue: qtserialport:

I checked PACKAGE_DEBUG_SPLIT_STYLE is not set globally - few recipes
set PACKAGE_DEBUG_SPLIT_STYLE to debug-without-src.

Help appreciated
