Yep!

According to 
	https://stackoverflow.com/questions/34879686/loading-gnu-ld-script-with-dlopen
and
	https://sourceware.org/legacy-ml/libc-alpha/2011-07/msg00152.html

It would probably a good Idea to expose the contents of gnu/lib-names.h
in case we are on a GNU-Libc system (like RHEL/Debian based as opposed to 
eg, musl-based systems such as Arch, or any other Unix  for that matter).

Should we hence put a category of well-known system library names
into primitives with default names as fallback?

such as

UnixFFI class>>libcName
	<primitive: 'primitiveLibcName' module: 'SqueakFFI'> "or something"
	^ 'libc.so' "unixy default"

(I'm making thinks up as I go…)
