meta-ast2500: Add tune file for ARM1176JZ-S

Add a tune file for the ARM1176JZ-S without the VFP FPU.

The Raspberry Pi machine layer contains a tune file for ARM1176JZF-S
which has a VFP FPU.

In addition to adding a core-specific compiler tuning option, this tune
enables packages to be compiled to emit Thumb instructions if
  ARM_INSTRUCTION_SET = "thumb"
which will generate slower but more compact code.

Note that packages default to ARM-only code and even if enabled, the
compiler may choose not to emit Thumb code. Packages built with Thumb
support will have this reflected in the naming (armv6t instead of
armv6) but the architecture name will remain armv6.

Tested: Included the file into the build and verified it has no effect.
