[commit] Test adjustments for Symbian OS

[Daniel Jacobowitz <drow at false dot org>]

Three obvious changes:

  - This is the first remote target with args support but no
  watchpoint support, so commands.exp was not prepared.
  - float.exp should allow ARM targets without an FPU, since the XML
  descriptions support this.
  - The Symbian linker directs calls to global symbols through PLT
  entries even within a single executable.

Tested arm-symbianelf and x86_64-linux, checked in.

	* gdb.base/commands.exp (watchpoint_command_test): Handle
	gdb,no_hardware_watchpoints.
	* gdb.base/float.exp: Allow ARM targets without floating point.
	* gdb.base/step-test.exp: Allow callee@plt when stepping in.
