It's important to test string functions for both endiannesses, since they 
can easily have endian-specific bugs.  You should be able to run string/ 
tests for big-endian with QEMU userspace emulation, for example, if you 
don't have an actual big-endian system to run tests on (some parts of the 
glibc testsuite, such as threading tests, may have problems with QEMU 
userspace emulation, but for string tests it should be fine).
