+    Setup .pc file to allow use for cross-compiling
+    
+    The Makefile is currently creating the pkg-config file using static lib
+    and include dir statements. Change that so that projects that
+    cross-compile hiredis can use pkg-config to setup other programs
+    depending on it.
+    
+    Note: these projects (like OpenWrt) call pkg-config with arguments to
+    overwrite some variables in the .pc file, namely:
+    
+    --define-variable=prefix=<...>
+    --define-variable=exec_prefix=<...>
