You use PKG_CONFIG_FOR_BUILD, along with CC_FOR_BUILD etc.

This is for when cross-compiling a package that needs a native tool,
and building that tool is easiest with pkg-config.  The pkg-config
binaries *need* to have different names.

Concrete example: I've a patch to GTK+3 which uses
PKG_CONFIG_FOR_BUILD to find a host gdk-pixbuf so it can build a
native gtk-update-icon-cache instead of depending on gtk+3-native.
This pkg-config needs a different name as otherwise it would be used
instead of the cross-pkg-config.
