crunchide: Correct 64-bit section header offset

For 64-bit binaries the Elf_Ehdr e_shoff is at offset 40, not 44.
Instead of using an incorrect hardcoded offset, let the compiler
figure it out for us with offsetof().

crunchide(1): support non-custom elf object layout

The crunchide utility presumes the last 3 chunks of an ELF object
layout are section headers, symbol table, and then string table.
However, this is not specified in the ELF standards, and linkers
may generate different layouts when doing partial linking (-r).

This change is required to build FreeBSD with mclinker or the
gold linker.

Fix crunchide to work on sparc64 and perhaps other 64 bit platforms.

I used the wrong type when setting st_name in the symbol table entry
struct. It's an Elf64_Word which is defined as an unsigned 32 bit int
on both 32 and 64 bit platforms.

To make things sensible, define some new macros to use as "word" macros
and use those, rather than simply using the explicit 32 bit macros.

Port over changes to the crunch symbol hiding method from NetBSD.

The older symbol hiding method breaks for MIPS. This implements
symbol hiding through renaming to a symbol name which is highly
unlikely to clash.

The NetBSD code didn't use byte-swapping macros for endian-awareness;
so it didn't work when cross-compiling a MIPS world on i386/amd64.
This patch includes those (as best as I could figure what they
should be) and has been tested to generate valid MIPS crunch
binaries both cross- and native- compiled.

o Redefine Elf64_Word to be 32-bit,
o Add Elf64_Xword and Elf64_Sxword for 64-bit entities,
o Use Elf_Size in MI code to abstract the difference between
Elf32_Word and Elf64_Word.
o Add Elf_Ssize as the signed counterpart of Elf_Size.
