autobuild[sn-devel-144]: intermittent test failure detected

[autobuild]

The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-07-13-1810/flakey.log

The failure seems to be in the "ctdb" suite, whose build logs are available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-07-13-1810/ctdb.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-07-13-1810/ctdb.stdout
  
The top commit at the time of the failure was:

    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.
