Ah, right. I see.
I wonder if we should just give insane.bbclass a whitelist of
directories in which it should ignore apparently misplaced libraries.
 There aren't likely to be many cases like that one.
Or alternatively, add an extra check so that when it thinks it's found
a misplaced library, it checks the ELF header to make sure that it
really is one and suppresses the diagnostic if not.  If you only do
this in cases where it was about to print a warning anyway then the
impact on performance shouldn't be too bad.
