Added the TOOL_PREFIX variable for setting up the executable tools.

Browse source 
Currently three different tool chains seem to be used:
   * avr-*
   * pic32-*
   * arm-none-eabi-*

These all get set up independently. This patch centralizes the
definitions of the executable tools and does it generically, by means
of the newly introduced TOOL_PREFIX variable. Setting up a
tool chain is now simply a matter of defining the TOOL_PREFIX
variable. For the currently supported tool chains it gets set to avr,
pic32 or arm-none-eabi. Arbitrary tool chains can now easily be set up,
by the TOOL_PREFIX variable.

Although the use of the OVERRIDE_EXECUTABLES variable is now almost
not justifiable, it was left as-is, in order to assure backwards
compatibility.

The tool prefix, which gets prepended to the tools like $(TOOL_PREFIX)-gcc, $(TOOL_PREFIX)-g++, etc.
The following tools will be prefixed with '$(TOOL_PREFIX)-':
* gcc
* g++
* as
* objcopy
* objdump
* ar
* size
* nm
Defaults to `avr`

```Makefile
TOOL_PREFIX = arm-none-eabi

Override the default build tools. Override the default build tool paths and names.
If set to `1`, each tool (`CC`, `CXX`, `AS`, `OBJCOPY`, `OBJDUMP`, `AR`, `SIZE`, `NM`) must have its path explicitly defined. See `chipKIT.mk`. If OVERRIDE_EXECUTABLES is defined, all tools (`CC`, `CXX`, `AS`,
`OBJCOPY`, `OBJDUMP`, `AR`, `SIZE`, `NM`) must have their paths
explicitly defined. This may be used in the rare case where
overriding a path and/or executable name is required.
The "?=" assignment cannot be used because the executable tags
are already implicitly defined by Make (e.g. $(CC) == cc).
