According to the Debian bug report, it was not just about
config.log.  It fixed a problem for the submitter, although he
didn't specify the problem precisely.

>From http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=221148:

    The command (indirectly) passed to AC_TRY_COMMAND by AC_TRY_COMPILE
    produces a multi-line command that eval doesn't like (syntax error
    before unexpected "||"). The attached patch fixes this by causing the
    command to span only one line in the generated configure script.
