Applied to next, but after doing quite a number of changes:

    [Thomas:
     - drop the dependency on host-bdwgc, since it is not needed. Only
       host-guile will need host-bdwgc, but bdwgc itself doesn't need
       host-bdwgc.
     - add dependency on host-pkgconf, needed to detect libatomic_ops
     - add --with-libatomic-ops=yes to force bdwgc to use the system
       libatomic_ops, and not the internal one.
     - instead of using BDWGC_LIBTOOL_PATCH = NO (needed to avoid patching
       libtool because the libtool version used by bdwgc does not have a
       corresponding patch in Buildroot), use BDWGC_AUTORECONF = YES,
       which generates a proper libtool (without this, some -L/usr/lib
       flags are added by libtool).]
