It is, however, the only current solution, until libtool is fixed.

What's more, it can be automated, using sed.

Oh?  That would be a different bug.  Could you go into more detail?

Fix libtool.

libstdc++ is not responsible for the .la file; we are using a tool that
is managed by a separate project:

    http://www.gnu.org/software/libtool/libtool.html

The bug is that there is no easy and correct way to take -L/path and -R/path
and decide whether "/path" is a directory that should be remembered for
later use, or whether it's pointing into a temporary directory.  If you
have suggestions for a fix or a workaround, please contact the libtool
mailing list.  :-)

The problem is not unique to libstdc++, either.  Any shared library built
using libtool and using transient -L/-R paths will find them in the .la file.
