Fix segfaults on SELinux machines; fixes #7629
Patch from wgmitchener.
From the ticket:
The two addresses (adjustorStub and code) contain the same memory
(double-mapped), but one is writable while the other is executable.
This is how libffi works around the SELinux restrictions. On
non-SELinux systems the code and data addresses are probably the same.
