And then what? If you need a different SDK with the same triplet, you have th 
same cross-tool names, so you need a different directories prefix. pkg-config 
makes no difference here: first and foremost, you need to point to the correct C 
compiler and C headers and run-time libraries.

Just like if you *natively* build for a different distro.

Point being, this has nothing to do with pkg-config and nothing to do with 
cross-compilation, and thus I don't see why there should be a cross-
compilation-specific pkg-config-specific flag for that.
