Build i386.rpm libgomp and libsupc++.a(guard.o) as i486+, pre-i486
hardware isn't supported because NPTL doesn't support it anyway.

2008-03-27 Jakub Jelinek <jakub@redhat.com>
* libgomp.h (struct gomp_team_state): Remove single_count field
ifndef HAVE_SYNC_BUILTINS.
(struct gomp_team): Likewise. Add work_share_list_free_lock
ifndef HAVE_SYNC_BUILTINS.
* team.c (gomp_new_team): If HAVE_SYNC_BUILTINS is not defined,
don't initialize single_count, but instead initialize
work_share_list_free_lock.
(free_team): Destroy work_share_list_free_lock ifndef
HAVE_SYNC_BUILTINS.
(gomp_team_start): Don't initialize ts.single_count ifndef
HAVE_SYNC_BUILTINS.
* work.c (alloc_work_share, free_work_share): Use
work_share_list_free_lock instead of atomic chaining ifndef
HAVE_SYNC_BUILTINS.
2008-03-26 Jakub Jelinek <jakub@redhat.com>
* loop.c (gomp_loop_init): Fix GFS_DYNAMIC ws->mode setting.
