	  Enabling this option will compile and install the getconf,

	  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.
