The following method relies on the fact that sparcv9 ABI maximal
page length is 1MB and all ELF segments on sparc64 are aligned
- to 1MB. Also, it relies on _DYNAMIC coming after _GLOBAL_OFFSET_TABLE_
- and assumes that they both fit into the first 1MB of the RW segment.
- This should be true for some time unless ld.so grows too much, at the
- moment the whole stripped ld.so is 128KB and only smaller part of that
- is in the RW segment. */
