RECIPE_SYSROOT can retain a gcc-<old-version>/python directory left
over from before a gcc version bump, since sysroot cleanup does not
always remove it. gdb_pretty_print_scripts globbed usr/share/gcc-*/python
and silently picked the first match, which could be the stale, no
longer matching version, breaking libstdc++ pretty-printing in gdb
(register_libstdcxx_printers) without an obvious cause.

Raise a DevtoolError when the glob matches more than one directory
instead of guessing, and tell the user to remove tmp/work and rebuild
the recipe.
