grep: improve performance for older glibc
glibc has a bug where mbrlen and mbrtowc mishandle length-0 inputs.
Working around it in gnulib slows grep down, so disable the tests for it
and make sure grep works even if the bug is present.
* bootstrap.conf (avoided_gnulib_modules): Add mbrtowc-tests.
* configure.ac (gl_cv_func_mbrtowc_empty_input): Assume yes.
* src/searchutils.c (mb_next_wc): Don't invoke mbrtowc on empty input.
