This patch adds support for installing the gcc test suite. A helper
Makefile is provided for building and running the gcc tests.
The default configuration runs all gcc tests and requires automatic
ssh/scp login access to a networked target board. See README for
more details.
Note: Current feature is tested with the powerpc-unknown-linux-gnu
sample but it should work with others as well.
