Header Regeneration is Wonky on Rebuild

[dwbuiten]

Right now, header generation generates some weird broken header (with wrong types, for example), or doesn't regnerate the header(s) at all, even though the C library is rebuilt.

Example:

1. git clone https://github.com/xiph/rav1e/
2. cd rav1e && cargo cinstall --prefix=whatever
3. vim src/capi.rs and add a function or something
4. cargo cinstall --prefix=/whatever
5. Header is wrong.

If I run, e.g. git clean -fdx an then re-run cinstall, the header is generated correctly.

It is a subset of #21. as workaround you can remove the buildinfo file for now.

Ah, OK, I was not sure, but #21 reminded me when I saw it. Closing then.

We'd need to investigate why this happens though since in theory changing a file should trigger a rebuild in cargo and the rebuild should provide a different build info. If you could act as second brain here is where the bug could possibly be.
