This linker script is only enabled for systems with GCC or GCC-like compilers, though technically it should work on the BSDs too (will enable after testing). For regular modules, this declares one ELF version "Qt_5" and places all QtCore symbols inside, then it declares unused ELF versions "Qt_5.x" for each older minor release. For modules declared "internal_module", all symbols are placed in version Qt_5_PRIVATE_API. The big advantage of an ELF version is that, when we do Qt 6, both versions of QtCore could be loaded in memory without conflicts and all symbols would be resolved to the correct library. No module can talk to both at the same time, but this avoids mistakes of loading them indirectly by plugins. The extra Qt_5.x versions will be used in the next commit.
