meson.bbclass: warn if cross property defaults are used
The Meson idiom for checks which require running code on the target
(which isn't possible in cross compilation) is to use a cross property,
which the user can set in the cross file:
if cc_can_run
rres = cc.run(test_foo_code)
have_foo = rres.compiled() and rres.returncode() == 0
else
have_foo = meson.get_cross_property('have_foo', false)
endif
The default value may be overly conservative so we should review every
property and explicitly set them as apppropriate. oe-core 669ddaf added
a log message when the default value is used, so look for this message
and emit a warning that the user will see.
