Immediate expansion of perl_get_libdirs() is too early for
BBCLASSEXTEND. This results in a packaging QA error when building a cpan
recipe as nativesdk. The split debug files do not get picked up by the
dbg package because it looks in the wrong libdir.
The is_target() function remains because it is used elsewhere.
