+[PATCH] bindings/python: Allow hardcoded path to capability.h to be overridden
+
+Currently the path to capability.h is hardcoded. When cross compiling
+the host capabiity.h may be different to the target copy, leading
+to different options being encoded in the python bindings than
+expected. This causes a reproducibility issue amongst other potential
+problems.
+
+Add a configure option to optionally specify the right path to the
+correct header as its probably safer/more reliable than trying to
+query the compiler to get the header path.
