erl 17.3 config failre

Building either in local ports tree, or via poudriere:

checking for 1-stage DTrace precompilation... dtrace: failed to compile script emulator/beam/erlang_dtrace.d: "/usr/lib/dtrace/io.d", line 43: operator -> cannot be applied to a forward declaration: no struct devstat definition is available
configure: error: Could not precompile erlang_dtrace.d: dtrace -h failed
configure: error: /bin/sh '/wrkdirs/usr/ports/lang/erlang-runtime17/work/otp_src_17.4/erts/configure' failed for erts
===>  Script "configure" failed unexpectedly.

I believe that `dtrace -h` requires root privileges to run, not sure how that can work within poudriere etc, viz https://github.com/jj1bdx/erlang-freebsd-port#dtrace-support

Adding 
```
diff --git i/lang/erlang/Makefile w/lang/erlang/Makefile

 .if ${PORT_OPTIONS:MDTRACE}
 CONFIGURE_ARGS+=--with-dynamic-trace=dtrace
+NEED_ROOT=yes
 .else
 CONFIGURE_ARGS+=--without-dynamic-trace
 .endif
```

I'm not clear how to apply this to my poudriere setup for testing, but I guess it would work fine as well there.

DTrace + OTP is a wonderful combo, I hope we can find a fix for this!

bumping this...
Comment 5 Jimmy Olgeni freebsd_committer freebsd_triage 2016-01-20 10:31:53 UTC 
NEED_ROOT is no longer supported, but as of r406740 everything should work as expected on R18.
