Executables in the toolchain archive occasionally contain runtime library search paths (RPATH) that use the $ORIGIN placeholder. However, in order for that placeholder to work, /proc must be mounted. When iceccd executes the toolchain in the chroot environment, it doesn't mount /proc, so it is unable to resolve $ORIGIN resulting in a failure to find dynamic libraries. The fix is to replace $ORIGIN in executable RPATH entries with the known chroot executable path. In order for this to work, the actual real path to the executable must be resolved to remove any symlinks, otherwise the calculate $ORIGIN replacement will be wrong. This is done by using "readlink -f", which is an acceptable dependency because Yocto already requires it.

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.
