branches:  trunk
changeset: 446145:928f1f997917

description:
When compiling with -fwhole-program gcc will omit functions which
are not used in the file, even if not declared static.
Add __attribute__((externally_visible)) to memcpy() to force gcc to
include it.
Fixes build on -current (gcc 9)
This is a build fix so no PKGREVISION bump
