Remove unnecessary linker flags from JNI host build (#30206)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/30206
- --whole-archive isn't needed because we link libtorch as a dynamic
dependency, rather than static.
- --gc-sections isn't necessary because most (all?) of the code in our
JNI library is used (and we're not staticly linking libtorch).
Removing this one is useful because it's not supported by lld.
Test Plan:
Built on Linux. Library size was unchanged.
Upcoming diff enables Mac JNI build.
