boost-build-native: workaround one rarely hang problem on fedora34
Reproduce scenes: * On fedora34 * autofs.service is started * test is nis user, which mounted at /nis by autofs * under /nis/test, there are symlinks point to another nis mount point /nis/yan Result: task boost-build-native:do_install hang forever NOTE: recipe ovmf-edk2-stable202102-r0: task do_package_write_rpm: Succeeded NOTE: Running noexec task 8124 of 8152 (/layers/oe-core/meta/recipes-core/ovmf/ovmf_git.bb:do_build) Bitbake still alive (5000s) Bitbake still alive (10000s) Bitbake still alive (15000s) Bitbake still alive (20000s) Bitbake still alive (25000s) Bitbake still alive (30000s) Bitbake still alive (35000s) Bitbake still alive (40000s) Bitbake still alive (45000s) Bitbake still alive (50000s) $ps aux | grep b2 test 2773444 0.0 0.0 13532 2748 ?

This maybe caused by abnormal status of autofs.service. The problem cannot reproduce after restart autofs.service. There should be an autofs bug. and there is an autofs hang problem bug on fedora34 on it's bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1953390 Workaround: Since b2 don't actually write something to HOME dir, change HOME dir to /var/run, a dir not mounted by autofs.
