The new 'split_libmodules=yes' option is useful to work around linker command line size limitations when linking a huge number of objects. We're currently over 64k chars when linking libmodules.a on Windows with MinGW, which triggers issues as seen in #30892. Even on Linux, we can also reach linker command line size limitations by adding more custom modules. We force this option to True for MinGW on Windows, which fixes #30892. Additional changes to lib splitting: - Fix linking of the split module libs with interdependent symbols, hacking our way into LINKCOM and SHLINKCOM to set the `--start-group` and `--end-group` flags. - Fix Python 3 compatibility in `methods.split_lib()`. - Drop seemingly obsolete condition for 'msys' on 'posix'. - Drop the unnecessary 'split_drivers' as the drivers lib is no longer too big since we moved all thirdparty builds to modules.
