[boost] reuse of strip-debug-rule

Hi, the rule turn-off-intel-debug-symbols is now defined/used at least in 3 libraries: graph, python and spirit. There is another similar one ("special-requirements") in multi_index which does the same thing for GCC on Tru64. Does it make sense to provide a common rule for this case that accepts the OS and a wildcard for the toolset as parameter? Where could this rule be defined? Stefan
