Prefer MACHNE_CPUARCH to MACHINE_ARCH in most contexts where you want
to test of all the CPUs of a given family conform.

16c6e0979c correct description of how a string is stored, fix a few
typos and reference the kernel file which processes this info.

All in all, the content of this file should be moved to kldxref.c
or to the kld(4) manpage.

ddce581880 Make the linker.hints file have mode 644 instead of 600.
There is nothing secret in the file, and the missing read
permission breaks diskless operation.

0aad0f2282 These are the things that the tinderbox has problems with because it
doesn't use the default CFLAGS which contain -fno-strict-aliasing.

Until the code is cleaned up, just add -fno-strict-aliasing to the
CFLAGS of these for the tinderboxes' sake, allowing the rest of the
tree to have -Werror enabled again.

2fdfd0fee2 Use safe strlcpy rather than unsafe strncpy. After marcel's last fix,
there was still one overflow possible.  strlcpy is faster anyway
because it doesn't unexpectedly zero the entire length of the string
when copying short strings....

77a6f8ac6f Fix (static) buffer overflow bug. The dest buffer is of size MAXPATHLEN,
so dest[MAXPATHLEN] falls outside the buffer.  This bug corrupted
arenas[0] defined in libc's malloc.c on PowerPC when kldxref is shared,
which triggered a delayed SIGSERV.

259d74ed53 Link kldxref(8) static on PowerPC to work around a SIGSEGV that
cannot easily be analyzed due to there being no debugger yet.
The SIGSEGV only happens when kldxref is linked shared.
Since kldxref(8) is needed for a release build, having it not
dump core is important.

9ceddbd532 Change maketempfile() to return a FILE* so as to eliminate the fopen()
that immediately follows the only call to it. maketempfile() uses
mkstemp(), so the temporary file has already been opened and using
fopen() again just opens the file twice. This also fixes the invalid
mode used on the fopen().
While here, assign NULL to fxref after fclose() because we test for
fxref being !NULL to determine if we have the (temporary) hints file
open.

757686b115 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.

9dba198b0e Explicitly pass in the relocation base and data offset into ef_reloc()

relocation schemes. Also add some comments and improve variable

23d0f849c5 Add MD relocation support for amd64 and i386 platforms. The no-op
relocation is not sufficient for ELF relocatable object format
modules, since accessing the module metadata involves following
pointers between different ELF sections.

This allows kldxref to correctly build linker.hints on the amd64
platform.

pointers and remove knowledge of the file format from kldxref.c.

1eed250ad8 Fix kldxref on sparc64 by allowing non-trivial relocations to be performed
on variables read out of raw kld files.  Unlike other platforms the value
will be in an Elf_Rela, not in the data section of the elf file.
