states that `DT_SUNW_FILTER` has the value `0x6000000e`, but this is
apparently only a human error - that would make the value collide with
the previous one (`DT_SUNW_RTLDINF`) and there is not even a single
source supporting this other than verbatim copies of the same table.

DT_SPARC_REGISTER was originally assigned 0x7000001. It is processor
specific, and should have been in the range DT_LOPROC-DT_HIPROC
instead of here. When the error was fixed,
DT_DEPRECATED_SPARC_REGISTER was created to maintain backward
compatability.
