Bug #18808: Cannot compile ruby 3.1.2 on powerpc64le-linux without disabling the jit features
https://bugs.ruby-lang.org/issues/18808#change-97997

* Author: npn (John Davis)
* Status: Feedback
* Priority: Normal
* Assignee: k0kubun (Takashi Kokubun)
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
The system I am trying to compile on is a ppc64el system running RedHat 7 (3.10.0-1160.62.1.el7.ppc64le).  I can successfully compile on a x86_64 system running the same version RedHat 7 (3.10.0-1160.62.1.el7.x86_64)

When I configure with the following,  make completes fine,  but if I remove the `--disable-jit-support` it fails with the following error.


     ./configure --enable-shared --enable-load-relative  --disable-install-doc --prefix=$RUBY_PREFIX --exec-prefix=$RUBY_PREFIX/rh_ppc --disable-jit-support
