RTL lacks support for `group` type sections. A `group` section requires
special link editor handling. The reference for the linker support is
https://refspecs.linuxfoundation.org/elf/gabi4+/ch4.sheader.html#section_groups
This ticket tracks adding `group` support.
The reason this has come to light is recent test results are reporting
`dl05.exe` failing. A recent patch to `libdl` has changed the symbol
loading. This is a two stage process, the first stage parses the symbol
records to determine the amount of memory to allocate and loading stage
fills the allocated table. A `group` section symbol is not being allocated
memory because the `group` section is not loaded however the filling stage
after allocation does not check for the section being present and adds the
symbol which overflows the allocated symbol table memory. There is no
overflow check because both stages are suppose to match.
