File 0009-configure.in-look-for-ncurses-pkg-config-first.patch of Package alsa-utils

Subject: [PATCH 09/13] configure.in: look for ncurses pkg-config first

Newer ncurses installs pkg-config files, and these are much easier
to manage when cross-compiling, so default to searching for those.
If they can't be found, we fall back to the existing xxx-config.
