Miri broken on Solaris - Githubissues

Running any program on Solaris fails since some recent rustc change:
error: unsupported operation: can't call foreign function `__sysconf_xpg7` on OS `solaris`

     = help: if this is a basic API commonly used on this target, please report an issue with Miri
     = help: however, note that Miri does not aim to support every FFI function out there; for instance, we will not support APIs for things such as GUIs, scripting languages, or databases
