ruby.c: initialize extra optional extensions linked statically

Browse source 
Add a hook point to initialize extra extension libraries. The default
hook function is replaced when linking a strong `Init_extra_exts`
symbol. A builder can insert an object file that defines Init_extra_exts
by XLDFLAGS.
