[oe] Building x86_64 target

[Michael Smith]

Hi,

I think there are a few people building for x86_64 using out-of-tree 
configurations. Here's my machine config for an HP Proliant server, for 
what it's worth. It contains a few ugly hacks. I've seen smarter, less 
ugly ways of doing it, submitted as patches - but I don't think they got 
applied up till now.

The config below was written before the staging changes a few months 
back, so there are some references to e.g. layout_libdir that may need 
to be changed to libdir.

##########################################
PREFERRED_VERSION_linux = "2.6.31"

TARGET_ARCH = "x86_64"

# We can't reuse the same -native builds as 32-bit machines, because
# ours need to be staged into staging/blah/lib64 instead of lib.
# Set blah to x86_64-buildoe64-linux to keep them separate.
BUILD_VENDOR = "-buildoe64"

layout_base_libdir = "${layout_base_prefix}/lib64"
layout_libdir = "${layout_exec_prefix}/lib64"

# Some packages install files into /lib/packagename, not /lib64/packagename.
FILES_${PN} += "${prefix}/lib/${PN}/*"
FILES_${PN}-dbg += "${prefix}/lib/${PN}/.debug"

# glibc's sysdeps/unix/sysv/linux/configure script only fixes
# libc_cv_slibdir if prefix is "/usr". With prefix of "", we need to fix it
# so libc libs don't get installed into /lib.
export libc_cv_slibdir="/lib64"

# Serial console settings for sysvinit
SERIAL_CONSOLE = "57600 ttyS0"
USE_VT = "0"

MACHINE_FEATURES = "kernel26 pci ext2 x86"

PREFERRED_PROVIDER_virtual/kernel = "linux"

KERNEL_IMAGETYPE = "bzImage"

MACHINE_EXTRA_RRECOMMENDS = " kernel-modules"

udevdir = "/dev"
OLDEST_KERNEL = "2.6.17"
GLIBC_ADDONS = "nptl"
GLIBC_EXTRA_OECONF = "--with-tls"

# Make task-boot include bootloader
MACHINE_ESSENTIAL_EXTRA_RDEPENDS += "syslinux-extlinux syslinux-mbr"
