I'm not using C++, my chip vendor is.  They have a huge module (the
source is 10MB compressed!) that enables all the chip features.  That
module compiles and insmod's fine when I use the algorithmics
toolchain for mipsel.  So it can't be a problem with the C++ source.

I don't really know how to read the following...  I looked for libgcc and
didn't find any references to it.  This is just the linking section, but I also
did "-v" when compiling all the .c and .cpp files, and saw no reference to
libgcc.
