'once' warnings from xs modules in perl 5.10.0

[Chia-liang Kao <clkao@bestpractical.com>]

Hi,

I noticed that in perl 5.10 i get an 'once' warning if i load an xs  
module who does a get_sv in boot.
Specifically this is the Subversion perl bindings generated by swig.

I wonder if it makes sense for that warning to come out from an xs  
module which supposedly knows what it is doing ?  in that case the  
following patch would silent the warnings from dynaloader. might need  
the similar fix to xsloader if this is the sane way to do it.
