The toolchain currently doesn't build for nommu ARM and is in need of serious work. Problem is there are no emulation targets and real ARM(7TDMI/720T/740T) hardware that's capable of running linux (enough memory, having a memory controller...) is VERY rare and uses very old versions to make it usable. The ARM nommu focus should go into Cortex M series processors that are obtainable at reasonable cost on modern hardware that has external memory controllers.

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.
