This warning is to remind you that glibc is a lousy library when it comes
to statically linking. You basically can't do it entirely. Even though you
specified -static, glibc still needs some dynamic libraries for certain
functions, and those can't be compile statically. You either heed the
warning and ship your app with those dynamic libraries (if they're needed),
or you can use another libc that's better suited to static linking,
like uClibc.
