Tests/LibELF: Test loading libraries with dynamic TLS

Browse source 
The setup is a bit peculiar: both the definition and the use site of
these TLS variables have to be in a shared library, otherwise the linker
might relax the global-dynamic access mode to something that doesn't
require a `__tls_get_addr` call.
