Currently, the Xtensa architecture uses the "snapshot" version of uClibc. This means that the build is not reproducible, since it will pick whatever latest version of uClibc is available at the moment of the build. This commit replaces that by adding a special Xtensa version, which points to a well-known Git commit. This is something we should hopefully be able to remove once the uClibc people realize that doing a 0.9.34 release would be useful. Should probably fix: http://autobuild.buildroot.org/results/5d6/5d6072a038acf894d832704e36c1d43f0254abf5/build-end.log at least I wasn't able to reproduce the build problem.

The test suite will be installed into /root/uClibc directory. To run

the test suite enter the /root/uClibc/test directory and type

"make UCLIBC_ONLY=1 CC=/bin/true check".

See the /root/uClibc/test/README for additional information.
