That works okay but adding `--enable-shared-host` is also required which causes the rest of the compiler to slow down.

>From https://gcc.gnu.org/install/configure.html:
```
--enable-host-shared

    Specify that the host code should be built into position-independent machine code (with -fPIC), allowing it to be used within shared libraries, but yielding a slightly slower compiler.

    This option is required when building the libgccjit.so library.

    Contrast with --enable-shared, which affects target libraries.
