Makefile.m32: deduplicate build rules [ci skip]

After this patch, we reduce the three copies of most `Makefile.m32` logic to one. This now resides in `lib/Makefile.m32`. It makes future updates easier, the code shorter, with a small amount of added complexity. `Makefile.m32` reduction: | | bytes | LOC total | blank | comment | code | |-------------------|-------:|----------:|-------:|---------:|------:| | 7.85.0 | 34772 | 1337 | 79 | 192 | 1066 | | before this patch | 17601 | 625 | 62 | 106 | 457 | | after this patch | 11680 | 392 | 52 | 104 | 236 | Details: - Change rules to create objects for the `v*` subdirs in the `lib` dir. This allows to use a shared compile rule and assumes that filenames are not (and will not be) colliding across these directories. `Makefile.m32` now also stores a list of these subdirs. They are changing rarely though. - Sync as much as possible between the three `Makefile.m32` scripts' rules and their source/target sections. - After this patch `CPPFLAGS` are all applied to the `src` sources once again. This matches the behaviour of cmake/autotools. Only zlib ones are actually required there. - Use `.rc` names from `Makefile.inc` instead of keeping a duplicate. - Change examples to link `libcurl.dll` by default. This makes building trivial, even as a cross-build: `CC=x86_64-w64-mingw32-gcc make -f Makefile.m32` To run them, you need to move/copy or add-to-path `libcurl.dll`. You can select static mode via `CFG=-static`. - List more of the `Makefile.m32` config variables. - Drop `.rc` support from examples. It made it fragile without much benefit. - Include a necessary system lib for the `externalsocket.c` example. - Exclude unnecessary systems libs when building in `-dyn` mode. Closes #9642
