    configure: Remove unused variable default_cflags

    configure has a variable default_cflags, which was originally added
    in commit bafe78ad3bc4c ("contrib/plugins: use an independent
    makefile") as part of it setting up the build environment for
    contrib/plugins, which at the time used make.  However, we now build
    the plugins with meson, and in commit 55c84a72aba4 ("contrib/plugins:
    remove Makefile for contrib/plugins") we dropped the logic from
    configure that does that makefile setup, leaving default_cflags
    as an unused variable.

    shellcheck helpfully reports this:
          default_cflags='-O0 -g'
          ^------------^ SC2034 (warning): default_cflags appears unused. Verify use (or export if used externally).

    Remove the unused variable.
