The RTLD_GROUP flag to dlopen comes from Solaris. It makes the symbol
resolution for dlopen not use the global symbols from the current team
(anything that's already loaded). The loaded object must be explicitly
linked against any symbol it needs to use (or it can use dlsym to search
symbols in the global scope explicitly).
This is also how symbol resolution worked in BeOS, meaning we already
have the code to do this, and just need to enable it.
This can be used in dosemu, where DOS-like executable are linked against
their own C library and should not use symbols from libroot.
Fixes#19674.
