At present, w_scalb_compat is used both for shared and static libm, for 
both old and new ports.

The proposed state is it would become more like the other w_*_compat 
files, which only build any code for shared libm for old ports - all the 
code in the files would be conditional on LIBM_SVID_COMPAT, so that static 
libm and new ports would end up using w_scalb instead (as would float128).
