A SOURCE_DATE_EPOCH of 0 might be misinterpreted by namely rpm as no SDE.
e.g.:
char *srcdate = getenv(SOURCE_DATE_EPOCH);
if (srcdate && rpmExpandNumeric(%{?clamp_mtime_to_source_date_epoch}))
Solve this by:
- providing a SOURCE_DATE_EPOCH_FALLBACK variable != 0
- changing defaults to use it
- using SOURCE_DATE_EPOCH_FALLBACK also when reading 0 out of sstate-cache

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.
