So, after reverting following patches (modulo test suite files that
can be skipped easily) from 2.29:


I got log.test running happily again.  Will try to identify which one
is to be blamed and follow up with binutils/ld maintainer.

There's also an obligation on the libqb side to make the configure
test much more bullet-proof, as having logging silently directed at
"virtual /dev/null" could be quite painful.  We might go as far
as refusing to compile when section attribute supported by the
compiler/GCC but linker being a show stopper -- I suspect the
performance is the key driver for using that mechanism, so silent
regression in this area might be undesirable as well.
