[PATCH v1 0/1] riscv: Nop out memcpy_noalignment if !IS_IN(libc)

[Yao Zihong]

This patch nop out memcpy_noalignment if !IS_IN(libc) since ld.so
can only use the generic implmentation.

Testing
-------
Testing was conducted on MUSE-Pi (SpacemiT M1). The glibc testsuite passed
without any additional regressions compared with glibc master in multiarch
and non-multiarch builds.
