[oe] apr-util_1.3.4.bb fails, looking at host includes

[Tasslehoff Kjappfot]

I'm trying to compile log4cxx, but it fails compiling apr-util, saying 
that it is looking at host includes.

I suspect the following from log.do_configure is a problem:

/checking for pg_config... /usr/bin/pg_config
   adding "-I/usr/include/postgresql" to CPPFLAGS
   adding "-L/usr/lib" to LDFLAGS/

But I have no idea how to fix it...
