I don't claim to be an expert(I don't even play one on TV :-).
The symbols missing are indeed functions to perform floating point
operations.  To find out more, there are two things you can do:

1) change your link line to add '-v' which will cause the compiler
   front end to dump the exact line that is passed to the linker
   (which should tell you where its looking for libgcc.a and libc.a)

2) change your link line to add '-Wl,-Map,' to genereate a
   linker map file in  By looking through that, you'll find
   what symbols are causeing what files to be link in(look for the
   LOAD lines).

I don't know.  the above two suggestions will give you more
information to figure it out.
