Here's the output of my "gcc -v":

Using built-in specs.
Target: mipsel-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Debian 4.4.5-8' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --program-suffix=-4.4 --enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.4 --libdir=/usr/lib --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --disable-libssp --enable-targets=all --enable-checking=release --build=mipsel-linux-gnu --host=mipsel-linux-gnu --target=mipsel-linux-gnu

My package version is actually slightly different than that, but your observation is correct. Unfortunately, I don't really know what that means in context. 

Is there something wrong with this configuration? Nothing seems to really jump out at me. If so, what can I do to fix it?
