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.

# Maybe makefile.inc1 should set TARGET_CPUARCH for the cross-tools, but

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.
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.
means:
o Remove Elf64_Quarter,
o Redefine Elf64_Half to be 16-bit,
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.

Back out the removal of custom version of endian.h system header.
On recent systems, it just falls back to <sys/endian.h>. But on
older systems like 5.0-DP1 or 4-STABLE, this private version may
be necessary, as crunchide(1) is a cross-tool for "make release".

longer includes machine/elf.h.
* consumers of elf.h now use the minimalist elf header possible.
This change is motivated by Binutils 2.11.0 and too much clashing over
our base elf headers and the Binutils elf headers.

Otherwise, an additional blank line is inserted.
