WIP add support for GNU LibC TLS model
...
Unlike on Windows, TLS index isn't part of the module format. glibc stores
it in the opaque link_map struct. There are many different heuristics
a debugger can use to locate it but most of them are unreliable and
prone to errors, or don't work when debugger attaches to a process.
We adopt the newer approach of looking for special symbols
in glibc that provide TLS index offset. These symbols were added in
2021, so programs linked with older glibc won't have TLS support.
