+configury forces pkg-config to poke for sdkdir variable which 
+pkg-config happily returns but does not prepend sysroot to it
+since thats only done for includes and libs. This then gets -I
+prepended and added to CFLAGS. Guess what gcc cross gripes
+about including host includes in cross builds but does not bail
+out the build but it does not escape the wrath of our oe's
+QA checks and rightly so. We replace use of sdkdir with 
+--cflags-only-I which returns the include paths correctly
+pointing inside sysroot and not at the host includes and plus
+includedir if you look inside the .pc file is assigned sdkdir
+anyway so we do not lose anything
+
+This m4 macro is included in other packages e.g. xf86-video-fbdev
+which dont build on hosts which have installation of
+xorg-xserver-dev because it gets this include poisoning
