  strstr, strcasestr: replace on platforms with broken memchr
  
  * modules/strstr: Split into...
  * modules/strstr-simple: ...new module that does not care about
  performance, but does care about glibc bug.
  * m4/strstr.m4 (gl_FUNC_STRSTR): Split...
  (gl_FUNC_STRSTR_SIMPLE): ...into new macro, which replaces strstr
  if platform memchr is broken, per Debian bug 521737.
  * m4/strcasestr.m4 (gl_FUNC_STRCASESTR_SIMPLE): React to broken
  memchr.
  * m4/memchr.m4 (gl_FUNC_MEMCHR): Only expand once.
  * doc/posix-functions/strstr.texi (strstr): Document the fix.
  * doc/glibc-functions/strcasestr.texi (strcasestr): Likewise.
  * modules/mountlist (Depends-on): Add strstr-simple.
  * modules/gen-uni-tables (Depends-on): Likewise.
  * modules/argz (Depends-on): Add strstr.
