opkg-build: Please fix the above errors and try again.
We suddenly get a much more usable error message. The traceback is supressed
as its distracting from the real problem in this case.
Ideally python itself would handle this but it doesn't so we have to
wrap the exception. We already do this in bitbake itself for the same reason.

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.
