 I've been able to consistently reproduce on my system here:
 
      NetBSD sakuracity 8.99.27 NetBSD 8.99.27 (GENERIC) #9: Sun Dec  9 
 12:07:19 PST 2018 
 root@sakuracity:/usr/obj/sys/arch/amd64/compile/GENERIC amd64
 
 I've been doing a bunch of digging.
 
 mcs.exe doesn't exist because the "mini" mono compiler 
 (${WRKSRC}/mono/mini/mono) segfaults any time it needs to do anything 
 interesting.
 
 Basically, any time we fork out to 'mcs' (those build lines prefixed 
 with "MCS  ", dozens and dozens of them), we're actually using the 
 "mini" mono program, which segfaults. But GNU make doesn't recognize a 
 program that has segfaulted to be one that failed. So it LOOKS like 
 we're happily "MCS"-ing when in fact we're not "MCS"-ing at all.
 
 Check out the backtrace.
 
      Program terminated with signal SIGSEGV, Segmentation fault.
