[BuildRules] Disable LTO flags for ROCM products

[smuzaffar]

I think problem is mixing LTO objects build with llvm (hipcc) and gcc. For now lets disable LTO for rocm products. I will check if for rocm products ( where .hip.cc files exists) we can compile default .cc files with llvm instead of gcc

Most likely we can - but I'm not sure if we should.
