lbmk sets TMPDIR to /tmp, and then creates a tmpdir, then exports *that* as the value of TMPDIR. this unified TMPDIR location then contains all subsequent files and directories, when any script or program makes use of /tmp, via mktemp. at least, that's the theory! in practise, because it was only being properly exported from the main build scripts, subscripts that are then called were not exporting it, at least that is my assumption because in some cases, i found that the coreboot build system was leaving errant files behind outside of our own TMPDIR, and that build system did not seem to be setting TMPDIR itself; more debugging is needed. anyway: use the exact same logic, but do it from err.sh. since err.sh is included from every lbmk script, that means it will always be exported when running every single part of lbmk. this should reduce the chance that mktemp creates files and directories outside of our custom TMPDIR location. this is because in lbmk, we mitigate unhandled tmpdirs/files by unifying it in the manner described, then deleting the entire TMPDIR on exit from the main lbmk parent process (the main script that the user called from, which is always the "build" file). in lbmk, effort is made to clean up temporary files properly, without relying on this catch-all, but we can't rely on that. the catch-all should also be as robust as possible.
