Mike Frysinger 1368b914e9 sim: testsuite: flatten tree
Now that all port tests live under testsuite/sim/*/, and none live
in testsuite/ directly, flatten the structure by moving all of the
dirs under testsuite/sim/ to testsuite/ directly.

We need to stop passing --tool to dejagnu so that it searches all
dirs and not just ones that start with "sim".  Since we have no
other dirs in this tree, and no plans to add any, should be fine.

The linker option is for sake of newlib, where the default program
layout starts at address 0. We need to change the layout so
there's no memory at 0, as all sim error checking is "lazy",
depending on lack of memory mapping. */
