file src/libstdc++-v3/config/linker-map.gnu has moved to src/libstd++-v3/config/abi/pre/gnu.ver, which cause FTBFS when cross compiling

Binary package hint: gcc-4.2

Hello,

I've tried to cross compile gcc on an x86, with the followings parameters:

GCC_TARGET=sparc
DEB_CROSS_INDEPENDENT=yes
DEB_CROSS_NO_BIARCH=yes

but the package ftbfs with this error while creating libstdc++6-4.2-dev-sparc-cross package:

cp -p /usr/src/gcc-4.2/gcc-4.2-4.2-20070609/src/libstdc++-v3/config/linker-map.gnu \
                debian/libstdc++6-4.2-pic-sparc-cross/usr/lib/gcc/sparc-linux-gnu/4.2.1/libstdc++_pic.map
cp: cannot stat `/usr/src/gcc-4.2/gcc-4.2-4.2-20070609/src/libstdc++-v3/config/linker-map.gnu': No such file or directory
make[1]: *** [stamps/08-binary-stamp-libstdcxx-dev] Error 1
make[1]: Leaving directory `/usr/src/gcc-4.2/gcc-4.2-4.2-20070609'
make: *** [binary] Erreur 2

The file seems to have moved to libstdc++-v3/config/abi/pre/gnu.ver

Thanks.
