Module Name:    src
Committed By:   pgoyette
Date:           Sat Mar 21 04:48:38 UTC 2020

Modified Files:
        src/lib/librumpuser: rumpuser_dl.c
        src/sys/rump: ldscript.rump

Log Message:
Teach rump how to process __link_set_sysctl_funcs so it can handle
modules the same as a real kernel.

Partly addresses PR kern/55088 - __link_set_evcnts not yet handled
(that will happen later)
