ptxd_lib_dgen: make sure <PKG>_CONFIG is only evaluated once
Packages may define <PKG>_CONFIG with '=' to avoid evaluating a complex
shell call if the package is not selected. However, this means the variable
is evaluated multiple time if the package _is_ selected.
Avoid this by overwriting the variable with itself using ':='.
