After make-4.3 migration child_execute_job function started using posix_spawn function, which happens to be broken on mips. It manifests itself as when make executed by root, it switches real user id to wrong value because of some issues with direct setresuid system call done in glibc __spawni_child function through inline assemble and/or gcc compiling it produces wrong code. I.e instead of passing -1 posix_spawn function incorrectly passes 127 as ruid. Subsequently job started by make can fail with permission issue because they run under wrong user. For now workaround is used by explicitly disabling posix_spawn call use by make on mips through configure variable.

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.
