This breaks hwdb: The path for the output file is hardcoded as
"${destdir}${rootprefix}/lib/udev/hwdb.bin"

Hmmm, maybe we could add '/usr' to the destdir. Please try that. This is
the '--root' argument the systemd-hwdb package.
If it works then the systemd-hwdb package should generate a hwdb that is
about 10MB in size.

If it works, remove the prefix instead of adding the rootprefix.
