Add $(GhcDynamic) knob, set to YES to get stage2 linked with -dynamic

Default currently NO.

Validate passed with GhcDynamic=YES on x86/Linux here.

The compiler is currently slower on x86 when linked -dynamic,
because the GC inner loop has been adversely affected by -fPIC, I'm
looking into how to fix it.
