pseudo: Drop nativesdk wrapper and link against old memcpy symbol
The -nativesdk pseudo wrapper setting LD_LIBRARY_PATH turned out to be a
bad idea since it can mix up different libc and lib-dl verisons which
may or may not work depending on the phase of the moon.
As an alternative to solving the original problem, this patch drops the
symbol version requirement on memcpy which allows pseudo to work with
libc's back to 2.7 which should be sufficient for our supported targets
using nativesdk.
