OK, so:

Good.

But then we have:
```
configure:33059: checking whether dtrace USDT is available
configure:33088: x86_64-pc-linux-gnu-gcc -c -O2 -pipe -march=native -fno-diagnostics-color -fno-strict-aliasing -fPIC  conftest.c >&5
conftest.c: In function 'main':

      | ^~~~~~~~~~~~~

configure:33105: result: no
configure:33140: error: --enable-dtrace, however, USDT is not available
```
