    x86: strip debug info for intermediate linking steps
    
    Linking debug info takes time, especially for xen.efi. At the same time
    symbol table contents aren't affected by presence / absence of debug info
    in the linked binaries (the ELF and COFF symbol tables would have extra
    section symbols, but tools/symbols omits those anyway).
