[RFC v1 1/1] devtools: allow libraries with no global section

[Paul Szczepanek <paul.szczepanek@arm.com>]

If a library has no global section in the version.map
allow it not to have symbols and not report it as an error.
This happens if a library doesn't export any functions
if they're all inline.
