55ae12052c Add support for one-byte relocations 
Add OUT_REL1ADR (one-byte relative address) and support for
OUT_ADDRESs with size == 1.  Add support for it in
outbin and outdbg.  *It still needs to be added to other backends*,
both the OUT_REL*ADR and OUT_ADDRESS codepaths need to be handled.

7c8c258cdd coff: Fix section alignment computation 
Section alignment is broken due to not being
direct "align -> power of two set" mapping but
rather including second addition operation.

Fix it by introducing coff_sectalign_flags helper.
This also allow us to use this helper for getting
rid of open coded computation as well.

2ddcd03900 Elf: bind labels to text section by default 
In case if SECTION directive is omitted but the real
code exist we form .text section by default and put compiled
code here. In turn labels are not handled in a same manner.

So lets bind them to text section by default as well.
