Extend the functionality provided by commit [1] to the SDK as well. This way we can make sure that nativesdk-binutils finds SDK libraries first rather than host ones. This is useful for example when trying to build the linux kernel using nativesdk-gcc. This scenario currently fails because it tries to link to host libraries rather than SDK host ones: make x86_64_defconfig make bzImage ... error: Cannot generate ORC metadata for CONFIG_UNWINDER_ORC=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel Makefile:1101: recipe for target 'prepare-objtool' failed make: *** [prepare-objtool] Error 1 .... /../../../../x86_64-wrlinuxsdk-linux/bin/ld: /lib/x86_64-linux-gnu/libpthread.so.0: undefined reference to `__libc_vfork@GLIBC_PRIVATE' ... [1] 15049c610b [buildtools-tarball: Add an ld.so.conf for nativesdk-binutils] (From OE-Core rev: 7ec84a463ad4c45aee9cd2cbc75b43e5aab5cd18) Signed-off-by: Ovidiu Panait <ovidiu.panait@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
