Thanks. I noticed that due to the commit 89edb2e8c6a7 ("riscv: Resolve 
calls to memcpy using memcpy-generic in early startup") already adding
__memcpy_generic to sysdeps/riscv/multiarch/dl-symbol-redir-ifunc.h, 
this is now duplicated:

diff --git a/sysdeps/riscv/multiarch/dl-symbol-redir-ifunc.h b/sysdeps/riscv/multiarch/dl-symbol-redir-ifunc.h
index 69a0790838..a4ff47107b 100644
