Improve sequence logic in cxx_init_decl_processing
Checking for one_only/weak support is better done
before deciding to turn references to __cxa_pure_virtual weak.
This helps at least on VxWorks where one_only / weak support
varies between kernel and rtp modes as well as across VxWorks
versions.

* decl.c (cxx_init_decl_processing): Move code possibly
altering flag_weak before code testing it.
