Alexander Bokovoy 4e123c4682 wafsamba/samba_abi: always hide ABI symbols which must be local ...

binutils 2.31 is going to change how shared libraries are linked, such
that they always provide their own local definitions of the _end, _edata
and _bss_start symbols.  This would all be fine, except for shared
libraries that export all symbols be default.  (Rather than just
exporting those symbols that form part of their API).

According to binutils developers, we should only export the symbols we
explicitly want to be used. We don't use this principle for all our
libraries and deliberately don't want to have ABI versioning control for
all of them, so the change I introduce here is to explicitly mark those
symbols that will always be added by default linker configuration with
binutils 2.31 as local. Right now these are '_end', '_edata', and
'__bss_start' symbols.
