Note that, when doing cross-compilation, one knows (or should better
know) exactly what he/she is compiling. So, it's usual (at least ok)
to edit or generate the config.h file (or equivalent files) used at

To be honest, I did not really check what this is.
AFAICS, there is:
- only 1 feature check using "bug", which is for darwin, so not really
relevant to me (though I can try to find some solution for this, but I
have no way to test it);
- only 1 feature (but up-to 3 checks) using "value", this is about the
sys_nerr, sys_errlist support in the C-library. However AFAICS, these
checks are useless because nginx does implement its own
ngx_sys_errlist, and never uses the one from the C-library.
