On Android, I'm seeing these compilation errors:
../gllib/string.h:855:1: error: reference to overloaded function could not be
resolved; did you mean to call it?
_GL_CXXALIASWARN (memrchr);
^~~~~~~~~~~~~~~~~~~~~~~~~~
../gllib/string.h:1010:1: error: reference to overloaded function could not be
resolved; did you mean to call it?
_GL_CXXALIASWARN (strchrnul);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~
../gllib/string.h:1375:1: error: reference to overloaded function could not be
resolved; did you mean to call it?
_GL_CXXALIASWARN (strcasestr);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This patch fixes them.

* lib/string.in.h (memrchr, strchrnul, strcasestr): Disable
_GL_CXXALIASWARN invocation on non-glibc systems.
