riscv64: Workaround -Wstringop-truncation error

Browse Source 
On riscv64, the compiler complained:

     In file included from /usr/include/string.h:548,
                      from omxregister.c:42:

     cc1: all warnings being treated as errors

It seems that the -O optimization to generate arch assemblies
leads to different behavior between riscv and arm, x86.
Add -Wno-stringop-truncation CFLAGS to workaround the problem.
