[Bug] undefined symbols in libtvm_compiler.so

[petersktang]

Expected Behaviour: dlopen libtvm_compiler.so

loading succesful

Actual Behaviour: dlopen libtvm_compiler.so failed with undefined symbols

libtvm_compiler.so is built with undefined symbols, failing ctypes.CDLL("libtvm_compiler.so")

ldd -r build/py3-none-linux_x86_64/lib/* | grep undefined
