runtime: fall back to /proc/self/auxv in Android libs Android's libc doesn't provide access to auxv, so currently the Go runtime synthesizes a fake, minimal auxv when loaded as a library on Android. This used to be sufficient, but now we depend on auxv to retrieve the system physical page size and panic if we can't retrieve it. Fix this by falling back to reading auxv from /proc/self/auxv if the loader-provided auxv is empty and removing the synthetic auxv vectors. Fixes #18041.
