Andreas Krebbel b4cbbe8f72 S/390: Add support for pgste marker 
This patch adds a new S/390 specific segment type: PT_S390_PGSTE.  For
binaries marked with that segment the kernel will allocate 4k page
tables.  The only user so far will be qemu.

elfcpp is a C++ library for reading and writing ELF information.  This
was written to support gold, the ELF linker, and may not be generally
useful.

elfcpp does not do file I/O.  It deals only with offsets and memory
data.

For efficiency, most accessors are templates with two arguments: the
ELF file class (32 or 64 bits) and the endianness.
