[D-runtime] build with -fPIC by GDC

[Long Chang]

Hello ,


I build druntime in gdc,   the ASM code is not working with -fPIC .

Is there any way to skip the ASM code and make druntime work with -fPIC .

Is a schedule plan to bring druntime working with dynamic lib under
linux , or a roadmap something like this .
