If runqemu fails, there is some logic to run a set of commands to dump various bits of information that might help debug the issue (particularly in a busy situation such as on the autobuilder). However, when we try to run these we are inside the normal build environment which restricts commands to be run on the host to those specified in HOSTTOOLS. Since this isn't a place where host contamination is going to be a problem, override PATH to a reasonable default so that we run the actual host tools directly to avoid the issue. (Logically we would want to use the original PATH value here, but it is not easily accessible.)

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.
