On ELF we need to know which symbols are used in relocations to decide if
...
they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

Add a InitSections method to the streamer interface.
...
The ELF implementation now creates text, data and bss to match the gnu as
behavior.
The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.
A nice benefit is that -n is not required anymore when producing
ELF files.

Factoring and potential bug fix. The elf "flags" cannot be used as masks.
...
For example, setting STT_OBJECT (1) and STT_FUNC (2), should not produce
a STT_SECTION (3).
