memmem: rearrange memmem and expand memmem-simple modules Move all functional checks to memmem-simple so that one has a fully functional memmem by using just this module. Restrict the memmem module to performance checks only. Document exactly how the memmem and memmem-simple modules relate to each other. * m4/memmem.m4 (gl_FUNC_MEMMEM_SIMPLE, gl_FUNC_MEMMEM): Move the empty needle check from the memmem module to memmem-simple. Also expand the empty needle check to ensure the correct pointer is returned, not just a non NULL pointer. In gl_FUNC_MEMMEM, make the cross compilation check only consider the versions with performance issues. * doc/glibc-functions/memmem.texi: Rearrange the portability documentation to correlate with the rearranged checks.
