    x86: use constant flags for section .init.rodata
    
    LLVM 11 complains with:
    
    <instantiation>:1:1: error: changed section flags for .init.rodata, 
expected: 0x2
    .pushsection .init.rodata
    ^
    <instantiation>:30:9: note: while in macro instantiation
            entrypoint 0
            ^
    entry.S:979:9: note: while in macro instantiation
            .rept 256
            ^
    
    And:
    
    entry.S:1015:9: error: changed section flags for .init.rodata, expected: 0x2
            .section .init.rodata
            ^
    
    Fix it by explicitly using the same flags and type in all the
    instances.
