Subject: [Bug go/59433] [4.9 regression] Many 64-bit Go tests SEGV on Solaris

I'm seeing a massive improvement, but now some 32-bit tests that used to
work before are failing:
Running target unix
+FAIL: net
FAIL: runtime
-FAIL: os/user
+FAIL: log/syslog
+FAIL: net/http
FAIL: sync/atomic
The net failure is another instance of PR go/59431, which I still need
to analyse, but the log/syslog and net/http failures are different.
They both SEGV like this:
Program received signal SIGSEGV, Segmentation fault.

I suspect they are related to PR go/59431, too: this should only happen
if runtime_SysAlloc returned NULL, which only happens for unhandled mmap
return value, although I don't see that in truss. Need to investigate
in more detail.
