Trying to build an SDK for the Beaglebone
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ git checkout -b dora origin/dora
$ . oe-init-build-env
MACHINE is set to "beagleboard" in local.conf
$ ./environment-angstrom-v2013.06
$ bitbake meta-toolchain-sdk
SDK is generated, and installed in /opt/poky/1.5.1 (default)
The toolchain environment file is "sourced"
Then I try to build U-Boot-13.10 (with a minor patch)
$ make am335x_boneblack_config
$ make
After compiling a number of file, the linking of a library fails:

export LDFLAGS="-Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed"
From the error message I see:
"arm-poky-linux-gnueabi-ld.bfd -Wl,-O1 ..."
Note that $(CROSS_COMPILE)-ld.bfd is used, not $(CROSS_COMPILE)-ld
so the linker is linking with $(LDFLAGS) which contains switches to be
passed to the compiler, and bombs
Changing LD to:
export LD="arm-poky-linux-gnueabi-gcc
--sysroot=/opt/poky/1.5.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi"
Does not help, still you get the same error message with
$(CROSS_COMPILE)-ld.bfd called with "-Wl,..." arguments.
Only when I am setting LDFLAGS="", E.E: not passing arguments to I can
compile U-Boot.
It looks like the toolchain does not handle compiler linker flags
correctly and passes the arguments without parsing to the linker.
If you use the SDK, Is it wrong to do=
${LD} ${LDFLAGS} ??
U-Boot does this in several places?
Using the poky installation to
bitbake core-image-minimal
will complete the build of U-Boot-2013.07, but does not pass these options.
