Hi,
W have found found quick fix for this.  The errors disappeared when all
the build flags were cleared in mentioned python modules recipes. It
means TARGET_CFLAGS = "" LDFLAGS = "" CFLAGS = "" in module .bb file. It
was checked on the device that modules are visible in python and they
work. I don't know why this helped and also what was causing the issue.
Do you have any clues what was wrong and how to fix it in proper way?
