[Buildroot] [git commit branch/next] bdwgc: Add new package

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=b0476427f6c0036b7803d591a5394923c4b07142
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

bdwgc is a garbage collector for C and C++. The Boehm-Demers-Weiser
conservative garbage collector can be used as a garbage collecting
replacement for C 'malloc' or C++ 'new'.

[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).]
