Since we now have uClibc-ng, and it is used as the default uClibc version, there is no real need to keep the Xtensa version: this version is just a specific Git revision of uClibc master branch, and uClibc-ng is also based on uClibc master branch. In addition, since in the choice of uClibc versions, uClibc-ng is already *before* the Xtensa specific version, uClibc-ng has in fact already been the default uClibc version for Xtensa since uClibc-ng support was introduced. See for example: http://autobuild.buildroot.org/results/c85/c854fae31d82e0f11d5a8b5bfc196c29bd7e21db/config for a build on Xtensa with the internal toolchain, where in fact uClibc-ng is used instead of the Xtensa specific version.

This is useful if you want to check if the uClibc library is working

for your architecture and/or help developing uClibc.

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.
