This is really slow with we have 1000s of sections each with a corresponding
relocation section. Also, it is only used by the ELF writer to add
basic data, so there is no need to force a new layout pass.

Should fix PR8563.

it would be a bit too big :-)

just

.type   foo,@object

will produce an undefined reference to foo. On the other hand, a file with
just

.weakref bar, foo

will not. It is somewhat hard to support both in MC since both statements
should create the symbols. It should be possible if we really need to by
adding to the flags, but hopefully that is not necessary.

With this patch we do not produce a undefined reference in any of those cases.
The assembly file needs an actual use for the undefined reference to be
present.

This is in preparation for a patch implementing .weakref.

* If we have a M or a G, reject sections without the type
* Only parse the flag specific arguments if we have M or G
* Parse the corresponding arguments for M and G

We ignore the G arguments and flag for now.

Move the existing patching for undefined symbols so that all the patching
is done in the same function.
