Oh wait, tools/testing/selftests/nolibc/nolibc-test.c is compiled
twice. One for libc, one for nolibc. The test cannot use
_NOLIBC_OPTIMIZER_HIDE_VAR(), it breaks libc:
```
$ make -f Makefile.nolibc run-libc-test
nolibc-test.c: In function ‘test_abs_range’:
nolibc-test.c:1756:9: error: implicit declaration of function ‘_NOLIBC_OPTIMIZER_HIDE_VAR’ [-Wimplicit-function-declaration]
 1756 |         _NOLIBC_OPTIMIZER_HIDE_VAR(ll, l, i);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~
make: *** [Makefile.nolibc:278: libc-test] Error 1
```

What approach do you prefer?
