Allow more control of redefined prefix behavior

Currently the native Win32 builds default to redefining the prefix
variable in .pc files based on their installation paths. This behavior
is not always desired when pkg-config is being used in a traditional
fixed path environment (e.g., /mingw like /usr).

Allow the default to be set via configure switch
--enable/disable-define-prefix, and allow it to be set both ways at
runtime through the --[dont-]define-prefix pkg-config option.
