rS314054: Exclude -flto when building *genassym.o
Summary

The build process generates *assym.h using nm from *genassym.o (which is in turn created from *genassym.c).

When compiling with link-time optimization (LTO) using -flto, .o files are LLVM bitcode, not ELF objects. This is not acceptable in the genassym process so remove -flto from those ${CC} invocations.
