+Subject: [PATCH] Make.rules: fix build with make <= 3.81
+
+Building with host make 3.81 resulted in an issue where src/efivar.pc
+was never generated.
+Even by running 'make efivar.pc' inside the src directory, make always
+returned that there was nothing to do.
+This was not observed when using make 3.82 or 4.x.
+It is apparently caused by the assignment operators in the multi-line
+defines in Make.rules, which do not seem to be supported by make 3.81.
+By omitting the assignment operators, the rule works with both versions
+of make.
