buildhistory create .txt file bh_installed_pkgs.txt and bh_installed_pkgs_deps.txt while listing down installed package. These file is later removed in buildhistory_get_installed(). when multiple process runs in parellal there are chances to race for the file where one process created the file while another task remove the file right after it. using different file name for each process should avoid the race. So add PID to the file name to make it unique.

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.
