boost: fix re-execution of task

After building boost package, re-execution of boostconfig task followed by
re-execution of compile task is giving following error
"error: duplicate initialization of gcc with the following parameters" during compilation
It is because multiple entries of gcc are being added during boostconfig re-execution
there by failing the compilation.

The patch fixes adding multiple "Using gcc" entries into /tools/build/v2/user-config.jam
