coreutils configure script needs to know whether /proc/uptime is available, but this is not possible in a cross-compilation context. This leads to an uptime program that fails to work on the target, as it has been compiled without /proc/uptime reading support. This commit fixes that by telling coreutils at configure time that /proc/uptime will be available on the target (which seems to be a reasonable assumption on Linux systems). This commit is made with great inspiration from Thomas Petazzoni's patch to buildroot to fix the same issue.

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.
