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.

When running as pseudo-nativesdk, we might need to run host binaries

|
linked against the host libc. Having a 2.14 libc dependency from memcpy is
|
|
problematic so instruct the linker to use older symbols.
