Wrong interpreter of sgx_edger8r on target

[liux2085]

The interpreter of sgx_edger8r was set to be the path on build host.

root@intel-x86-64:/opt/intel/sgxsdk/bin/x64# file sgx_edger8r 
dynamically linked, interpreter /<TOPDIR>/tmp-glibc/sysroots-uninative/x86_64-linux/lib/ld-linux-x86-64.so.2

This leads the samples in SDK cannot be built.

root@intel-x86-64:/opt/intel/sgxsdk/SampleCode/SampleEnclave# make
make[1]: Entering directory '/opt/intel/sgxsdk/SampleCode/SampleEnclave'
/bin/sh: line 1: /opt/intel/sgxsdk/bin/x64/sgx_edger8r: No such file or directory
make[1]: *** [Makefile:222: App/Enclave_u.h] Error 127
make[1]: Leaving directory '/opt/intel/sgxsdk/SampleCode/SampleEnclave'
make: *** [Makefile:181: all] Error 2

Only after applying "patchelf --set-interpreter /lib64/ld-linux-x86-64.so.2 /opt/intel/sgxsdk/bin/x64/sgx_edger8r", the sample can be built on target.
