And replying to my own comment...

In the original patch commit:
"file 5.33 also misidentifies actual libraries as PIE executables"

Is there any actually difference between a library and a binary when
they are built with PIE?  Aren't the elf headers exactly the same? Note,
we have been detecting PIE binaries as application/x-sharedlib with
previous file versions.

So either:
1) original patch is fine, as we need to update the description of
STRIP_SHARED to include all PIE things, or
2) we need a STRIP_PIE variable.

Can someone confirm what we get with static PIE with gcc8+?  This will
make my decision.
