build: build with v8 gdbjit support on supported platform 
Build it with gdbjit support on supported platforms by default
allows debugging JIT-compiled code in gdb when it's also enabled
at run time (via --gdbjit). Simply building it in should not
incur an overhead if it's not also enabled at run time.
