We use dwarfsrcfiles in package.bbclass to list the source files used by a binary. This is done before they're stripped and linked to debug symbols in separate files. It is possible a binary may already have a link to separate debug symbols, e.g. some of the test binaries in lttng-tools ptest. In those cases, the linked binary may be changed by package.bbclass code whilst dwarfsrcfiles is reading it. That would result in a rare SIGBUS race causing the binary to fail. To avoid this, break the debug file search path so no other binaries are found. Also fix a segfault if no binary is specified while here.

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.
