[Buildroot] libstdc++.la and it's libdir

Hi,
I'm doing a personal project where I am building a new rootdisk for my
DNS-323 (an ARM machine).
I use buildroot from 20080430 (currently) with gcc-4.2.3. Although I
have a few patches to make things work, I don't have anything that
touches gcc.
Now over to my problem:
The libdir variable in libstdc++.la (residing
in /path/to/buildroot/build_arm/staging_dir/usr/arm-linux-uclibc/lib/libstdc++.la
file is wrong. It says:
libdir='/usr/arm-linux-uclibc/lib'
where I would have expected it to say:
libdir='/path/to/buildroot/build_arm/staging_dir/usr/arm-linux-uclibc/lib'
This causes problems when using libtool. I.e, I compile a c++ libary (in
this case libsigc++-2.0) and then that library gets in it's .la file a
dependency for /usr/arm-linux-uclibc/lib/libstdc++.la and when I in
turn compile a program that uses libsigc++ libtool fails because it
can't find /usr/arm-linux-uclibc/lib/libstdc++.la.
If I manually edit libstdc++.la for it to point to the correct place,
things work as expected when I recompile my dependent libraries.
Have anyone else had this problem and have any idea where I should look
for a more permanent fix instead of doing things manually. I know I can
probably use sed somewhere to change the offending line, but I would
really like to know why it sets it wrong the first time around.
Any help is appreciated.
