New description:

 Here we actually use the system-wide `pkg-config` if present to query both
 Sage's as well as the system's package-config (`*.pc`) files.

 If only Sage's `pkgconf` is available, `.pc` files (and hence the packages
 they belong to) installed outside of Sage still won't be seen by Sage's
 `pkg-config` wrapper script.

 It is therefore still recommended to have a system-wide `pkg-config`,
 despite Sage now having its own, e.g. to let R use graphics packages Sage
 doesn't ship.
