Since we now only support uClibc-ng, remove the version selection from the uclibc package. Note that the BR2_UCLIBC_VERSION_SUPPORTS_* hidden booleans, which were only used to allow each uClibc version to specify which thread implementation they support and on which architecture are removed. Now such architecture dependencies are directly encoded in the "Thread library implementation" choice.

Enabling this option will compile and install the uClibc test suite.

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.
|
|
|
|
This is not needed at all for normal builds, so you can safely say no
|
|
if you do not plan to dig into your C library.
