[PATCH] sim: rl78: move storage out of header

[Mike Frysinger via Gdb-patches <gdb-patches@sourceware.org>]

This port declares its pc variable in a header and then includes
it times.  This causes linker errors with newer gcc due to the
change in -fno-common behavior.  Move the storage to a C file so
we only have one instance of it in the final program.
