[patch] Fix for multiple initialization of ALF

[Don McCoy]

This patch fixes a problem when using the Cell/B.E. Math Library (CML),
in that ALF was being initialized twice.  The default behavior is
preserved.  The conditional VSIP_IMPL_HAVE_CML must be defined in order
to use CML's initialization and finalization methods.

Committed after approval off-list.

Regards,
