| Enabling this option will compile and install the uClibc test suite. |

| 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. |
