	all the files which use CURRENT_STACK_FRAME.

+     instead of X = B + A this does not work any longer, since ld
+     clears it.
+     
+     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.  */
