Once we are determined that CPUID instruction is or isn't supported resfore
initial state of the bit 21 of the eflag register. This reduces possibility
that the threaded program linked with libpng will die due to arrival of the
signal during probing for the CPU type. More proper fix has been committed
into the -current kernel and will be MFC'ed soon, but this workaround is
necessary for those with older systems.
Among other things, this should make Nautilus, Balsa and other multi-threaded
GNOME programs more stable, therefore update is recommended to all existing
users.
Bump PORTREVISION.
