Use software watchpoints if hardware watchpoints are not available when testing gdb.base/watch-bitfields.exp
There are targets GDB thinks support hardware watchpoints, but in reality they
don't. Though it may seem that hardware watchpoint creation was successful,
the actual insertion of such watchpoint will fail when GDB moves the inferior.

We can avoid these errors/FAILs by checking the board data and switching to
software watchpoints if the board does not support hardware watchpoints.

the target does not support hardware watchpoints.
