    Fix test-as-const-jmp_buf-ssp.c generation on gnu-i386
    
    hurd's jmp_buf-ssp.sym does not define any symbol.
    scripts/gen-as-const.py currently was emitting an empty line in that
    case, and the gawk invocation was prepending "asconst_" to it, ending up
    with:
    
    .../build/glibc/setjmp/test-as-const-jmp_buf-ssp.c:1:2: error: expected « = », « , », « ; », « asm » or
    « __attribute__ » at end of input
        1 |  asconst_
          |  ^~~~~~~~
    
            * scripts/gen-as-const.py (main): Avoid emitting empty line when
            there is no element in `consts'.
