[patch] [libstdc++ pretty-printer] Fix hook.in for x86_64

[Jan Kratochvil]

Hi,

hook.in was failing:

pythondir is /usr/lib/python2.6/site-packages/gdb
libdir is /usr/lib64
prefix is /usr
dir is /lib/python2.6/site-packages/gdb

Traceback (most recent call last):
  File "/usr/share/gdb/auto-load/usr/lib64/libstdc++.so.6.0.12-gdb.py", line 59, in <module>
    from libstdcxx.v6.printers import register_libstdcxx_printers
ImportError: No module named libstdcxx.v6.printers

prefix got set to "/usr/lib" but the code expects a trailing "/" (missing then
one "../" path component).


I have no technical GCC SVN check-in rights.


Thanks,
Jan
