[Boost-build] Broken support for $ORIGIN in gcc.jam

Hi Volodya,

As we discussed earlier on IRC, I need $ORIGIN to make my link=shared 
binaries portable. But <dll-path>'$(ORIGIN)' isn't working because the 
gcc toolset adds double quotes which breaks ld's understanding of the 
keyword. So instead of:
-Wl,-R -Wl,'$ORIGIN'
I get:
-Wl,-R -Wl,"'$ORIGIN'"

The double quoting is hard-coded at gcc.jam:798. My idea for a fix is 
some shell scripting in that action block, but perhaps there is a better 
way.

Thanks,
-Matt
