The Linux kernel doesn't even support i386 anymore, there is no NPTL support for i386 and uClibc-ng only supports NPTL on x86, so there is essentially no usable thread implementation. Most likely glibc and musl also don't support i386 either. So it's time to remove the support for this architecture variant.

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.
