  Low: explain mysterious lines in a public header (qblog.h)

Also fix the previous inversion of the expression that in fact did not
use to check for anything (for "assert(1)" being a NOOP).

  Log Message:
  -----------
  build: be more restrictive about QB_HAVE_ATTRIBUTE_SECTION

That's because the code relies on (fairly unportable) treatment by the
linker, specifically ld linker from binutils suite:

    <https://sourceware.org/binutils/docs/ld/Orphan-Sections.html>

and without that in place, QB_HAVE_ATTRIBUTE_SECTION cannot be enabled
as the __{start,stop}_SECNAME extern references in qb/qblog.h will not
get resolved at the link time.
