    LTO: Prevent -flto being used in main system libraries.
    
    There are subtle ways it can get broken specially in libc and libm.
    (-plugin-opt=-pass-through=-lc)
    Both libpthread.a and rtld-elf could have use of LTO but it is safer
    for now not to expose internals. (affects only static libs)
