[Boost-build] exception handling switch in gcc

In order to be able to turn on and off exception handling with the gcc toolset,
I would suggest adding the following two lines to v2/tools/gcc.jam:

flags gcc.compile OPTIONS <exception-handling>off : -fno-exceptions ;
flags gcc.compile OPTIONS <exception-handling>on : -fexceptions ;

Since at least one other toolset (darwin) derives from gcc, this will make this
option work on macs as well.
