Linking assembled objects without the GCC toolchain possible?

[Mayuresh Kathe]

I have been reading up on various web-pages about building full-blown 
applications using just assembler.

Most show examples that hook into external libraries (usually C) and 
tend to use the GCC toolchain for the process.

Is it possible to build applications using external libraries but only 
with the tools provided by binutils?

Thank you,
