config BR2_UCLIBC_INSTALL_UTILS

Enabling this option will compile and install the getconf,
ldconfig and ldd uClibc utilities for the target.
You can save ~32 KiB in target space by disabling them since
they're normally not needed.

help
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.
