It would still hard code parts of the build directory into the binary (i.e., make sure you don't have any embarrassing/privacy-leaking paths in your home directory structure), but would much lessen the risk of a stray data-directory. What do you think?

Here's yet another alternative: gdb already tries to locate data-directory in $BUILDDIR/share/gdb as part of the relocation logic; we can install a symlink there that points to $BUILDDIR/gdb/data-directory, or make a copy for platforms that don't support symlinks.
