Subject: [ruby-core:78679] [Ruby trunk Bug#13041] ruby 2.4 rc1 dtrace build	fixes

Issue #13041 has been updated by Vit Ondruch.


The "-xnolibs" is not supported by SystemTap :/

```
$ dtrace -xnolibs
/usr/bin/dtrace invalid option -xnolibs
Usage /usr/bin/dtrace [--help] [-h | -G] [-C [-I<Path>]] -s File.d [-o <File>]
```

Not sure if Nobu's patch covers this ...

----------------------------------------
In FreeBSD before 11.0, using dtrace -G or -h will not work in a jail or without dtrace kernel modules loaded unless the -xnolibs flag is passed as well. Since we build in jails, this is needed during our build, so we have this patch:

https://svnweb.freebsd.org/ports/head/lang/ruby22/files/patch-Makefile.in?revision=369732&view=markup

We have used it with ruby 2.2, and 2.3 for a long time. Please consider it or a similar change for Ruby 2.4
