Subject: [PATCH] octavePackages.audio: Run autoreconf hook on compiled sources

Nixpkgs commit a0b51629f9e6a43a0312299f11dd9597dd936484 switched where
audio gets it sources, from a release tarball to the actual upstream
sources. These sources include leftover config.guess and config.sub
scripts generated by upstream maintainer's bootstrap script. Their
bootstrap script uses wget to grab config.guess and config.sub files,
which we cannot do inside the Nix build environment. So we forcibly
remove the config.* scripts and run autoreconf ourselves (through
autoreconfHook).
