android, patch file not found

Hi, all:
according to
I tried to patch Tls.patch but it gives error info. if no file, what is the influence
to the building of andriod? the error info is below.
Any ideas? what should to do next to fix this?

frank@frank-laptop:~/mydroid/bionic$ patch -p1 < /home/frank/Android/Tls.patch
can’t find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
|diff --git a/libc/include/sys/tls.h b/libc/include/sys/tls.h
|index d59f1c3…9053f7f 100644
|— a/libc/include/sys/tls.h
|+++ b/libc/include/sys/tls.h
File to patch:
Skip this patch? [y]
