Without this patch, if some options in `Makefile` were set outside `Makefile` and no `Make.config` existed with the necessary options, builds could fail. [1][2][3]
Therefore include strictly necessary options in `Make.global` and include this in all the Makefiles before `Make.config`.

v2: Use `include` instead of `-include` to get a warning/error if it is not present. [4] v3: Change according to Frank’s comments [5]. • Delete options set in `Make.global` from other Makefiles. • Leave adding `-fPIC` to `C[XX]FLAGS` in `Make.config.template` as the flags get reset including `Make.config`. • Modify `newplugin`. v4: Actually provide a working patch. Thanks to Klaus [6]. • Only use `$(VDRDIR)` after it has been defined. • Escape `$` in Perl script `newplugin`.
