Description

Trying to build Ruby 2.6 on RHEL7, I observe the following test failure on RHEL7, but just on aarch64. The other platforms pass just fine:

  1) Failure:
TestJIT#test_compile_insn_local [/builddir/build/BUILD/ruby-2.6.0/test/ruby/test_jit.rb:64]:
Expected 3 times of JIT success, but succeeded 2 times.
script:
```
def foo
  a = 0
  [1, 2].each do |i|
    a += i
    [3, 4].each do |j|
      a *= j
    end
  end
  a
end
print foo
```
stderr:
```
JIT success (276.6ms): foo@-e:2 -> /tmp/_ruby_mjit_p20163u0.c
JIT success (347.3ms): block in foo@-e:4 -> /tmp/_ruby_mjit_p20163u1.c
MJIT warning: failure in loading code from '/tmp/_ruby_mjit_p20163u2.so': /tmp/_ruby_mjit_p20163u2.so: undefined symbol: __multi3
Successful MJIT finish
```
.
<3> expected but was
<2>.

I suspect this must be some combination of architecture/compiler (gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-16)), because I don't observe similar issues on Fedora.
