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.
