you'll probably need the following:
ld -o HelloWorld HelloWorld.o -lc <kinda libgcc.a somewhere> \
/usr/lib/crt0.a <some more stuff... YMMV>

if you want to know it exactly, do gcc -v HelloWorld.c, this will have
the above `ld� command line somewhere in the output.

Alternatively, try 
gcc -o HelloWorld HelloWorld.o
or
gcc -o HelloWorld HelloWorld.s

gcc is smart enough to deal with .s files (it assembles them) as well
as .o files (which it will link into the final executable). _And_ it
will link in the appropriate libs.
