Improve cross-building by honoring PKG_CONFIG from environment

Browse source 
This is in response to Debian bug #960165 by Helmut Grohne.
<https://bugs.debian.org/960165>

When cross-building, another pkg-config is used that accounts for the target
architecture.

The patch makes it possible to supply that via the PKG_CONFIG environment
variable and defaults to 'pkg-config' so no such variable defaults to
native build.
