Fat LTO objects in the static library embed original source paths in
.gnu.lto_* IR sections. Unlike DWARF output, these sections are not
affected by -ffile-prefix-map, causing TMPDIR references to survive
into the installed libsepol-staticdev package.

Hi Thomas,


Could you please provide the build steps to reproduce this QA failure? I 
can not reproduce the issue, even without applying this patch.


Thanks,

Yi
