If you just want to work around the memcpy 2.14 version bump, you can:
a) #define memcpy memmove


b) Use a memcpy wrapper that explicitely uses the old symbol, as
described in http://stackoverflow.com/a/8862631

This does work, I find strange your claim that “requirements for
memcpy@GLIBC_2.14 are inherited from libc.so”.
