The kernel doesn't have direct visibility to the ELF contents of shared
libraries. Add some prctl() interfaces which allow glibc to tell the
kernel where to find .sframe sections.

Note that those values have been bumped since Josh's v4. Therefore
Josh's related Glibc patch needs to be updated and Glibc needs to be
rebuild as well. Otherwise the Kernel won't be able to find any
.sframe sections for DSOs.
