    x86: quote section names when defining them in linker script
    
    LLVM ld seems to require section names to be quoted at both definition
    and when referencing them for a match to happen, or else we get the
    following errors:
    
    ld: error: xen.lds:45: undefined section ".text"
    ld: error: xen.lds:69: undefined section ".rodata"
    ld: error: xen.lds:104: undefined section ".note.gnu.build-id"
    [...]
    
    The original fix for GNU ld 2.37 only quoted the section name when
    referencing it in the ADDR function. Fix by also quoting the section
    names when declaring them.
