Comment:
Also, I haven't changed `make_check` because two tests are failing

Here are the commands that are failing, if anybody is interested -
- This one fails with "**error: the option \`Z\` is only accepted on the nightly compiler**" -

The latter one can be traced to the 5th line of `/builddir/rustc-1.59.0-src/src/test/run-make-fulldeps/link-cfg/Makefile` -
```makefile
-include ../tools.mk

	ls $(TMPDIR)
