Accept that glibc's statx() falls back for us

So we don't need to have a high kernel requirement on its account.

I needed to introduce a configure-time check because we need to include
a header to get the __GLIBC__ macro, but we can't include any header in
assembler until we know it's glibc (we need to know that the header is
assembler-safe). glibc, uClibc and MUSL do provide an assembler-safe
features.h, but Bionic does not.

And we need to know that it's glibc's implementation, since the fallback
was not required. The other three libraries may not implement such a
thing when they get around to adding the system call.
