+Subject: [PATCH] Use pkg-config to find tcl
+
+Instead of using hardcoded path for the tcl include folder
+use pkg-config to find the proper values.
+
+That way it won't use the system folders for cross-compilation.
+
+Also, extend the number of tcl versions to check (at the time of
+this commit oe-core provides version 8.6)
