    kallsyms: ignore ARMv4 thunks along with others
    
    [ Upstream commit a951884d82886d8453d489f84f20ac168d062b38 ]
    
    lld is now able to build ARMv4 and ARMv4T kernels, which means it can
    generate thunks for those (__ARMv4PILongThunk_*, __ARMv4PILongBXThunk_*)
    that can interfere with kallsyms table generation since they do not get
    ignore like the corresponding ARMv5+ ones are:
    
    Inconsistent kallsyms data
    Try "make KALLSYMS_EXTRA_PASS=1" as a workaround
    
    Replace the hardcoded list of thunk symbols with a more general regex that
    covers this one along with future symbols that follow the same pattern.
    
    Fixes: 5eb6e280432d ("ARM: 9289/1: Allow pre-ARMv5 builds with ld.lld 16.0.0 and newer")
    Fixes: efe6e3068067 ("kallsyms: fix nonconverging kallsyms table with lld")
