Bug Description

Attempting to cross-compile ncurses with xdeb results in failure when attempting to install pkg-config files. This is because autotools inferred that PKG_CONFIG_LIBDIR=/usr/$(HOST_GNU_TYPE)/lib/pkgconfig, which does not exist when configure is run. This results in configure disabling generation of pkgconfig's .pc files (which would have been put in the wrong location even if they had been generated).

The solution as far as I can see is to export PKG_CONFIG_LIBDIR in debian/rules and ensure that this directory exists when configure is invoked. A patch to accomplish this is attached.

This doesn't seem to be a problem any more with multiarch cross-building (https://wiki.ubuntu.com/CrossBuilding), which has dropped the old-style dpkg-cross-ish PKG_CONFIG_LIBDIR handling:

Would you object to considering this closed? It's a different build system, but (as the author) I consider xdeb a dead-end experiment at this point; it served its purpose, and its ordering heuristics may still be useful, but multiarch cross-building is a more future-proof approach.
