Thanks for the investigation! Yes, coverage should be enabled by default,
though the `—with-headers` seems to be deprecated:

https://gcc.gnu.org/install/configure.html#Cross-Compiler-Specific-Options

and is somewhat annoying as it copies headers into a `sys-include` directory.

I’ll try to get `—with-sysroot` working.

Cheers,
