With LTO enabled, GCC performs a link-time recompilation pass where
DW_AT_comp_dir is set to the build directory. The -ffile-prefix-map
flags from DEBUG_PREFIX_MAP are not applied to this attribute during
LTO recompilation, leaving a raw TMPDIR path in the split debug
symbols of libsqlite3.so.

Hello,
This workaround isn't needed until the following patch has been
applied:

Thanks, Changqing Li.
