Pushed to mob.  Tested on openSUSE and Debian riscv64 distros, but only 
via a qemu, not on real hardware.  The thing is enough to compile itself 
and the full testsuite, so it's reasonably complete (e.g. the fancy 
argument passing and long double support is there).  No compressed code is 
generated, inline asm isn't supported.  Given the limitations of the TCC 
code generator the quality of the generated code is on par with the other 
architectures (i.e. horrible :-) ).

I did my best to test the other targets, but only checked armhf, aarch64, 
i386 and x86-64 on linux; i.e. the windows backends weren't checked.

Still, have fun.


Ciao,
Michael.
