MFC r308772: crunchide: report explicit error for combined string table

Some tools produce objects with a combined strtab and shstrtab.
These objects are not supported by crunchide since it rewrites the
symtab and strtab to "hide" symbols. This invalidates section header
offsets into a combined strtab/shstrtab.

In the future we could support these objects (by ensuring that we retain
unmodified section name strings in the output .strtab, and then rewriting
each section header's sh_name).

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 on MIPS with other than the O32 ABI.

It turns out that TARGET_CPUARCH doesn't buy us much here, if anything, but
costs us another copy of the transform. Revert it.

# Maybe makefile.inc1 should set TARGET_CPUARCH for the cross-tools, but
# it doesn't now. That would solve problems in other places too.

Submitted by: jmallet@

Use TARGET_CPUARCH instead of TARGET_ARCH here. Define TARGET_CPUARCH
based on TARGET_ARCH. Use TARGET_ARCH still for a powerpc64 test.
Futureproof for coming mipsel/mipseb and arm/armeb rename.

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.

Make our ELF64 type definitions match standards. In particular this
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.

our base elf headers and the Binutils elf headers.
