How do we build/make one dynamic link .so file from many C source TUs
(translation units) as
gcc -o foo.so -shared -fPIC foo.c
of a single .c file ?

gcc -o foo.so -shared -fPIC foo.c bar.c baz.c
Or compile each TU to an object file separately and link the objects:
gcc -c -fPIC foo.c
gcc -c -fPIC bar.c
gcc -c -fPIC baz.c
gcc -o foo.so -shared -fPIC foo.o bar.o baz.o

just curious,
it's actually g++ executable or (from gcc command silently passed to)
ld executable task/processs ?

gcc/g++ invokes ld. You can see this if you pass the -v flag. Well,
actually it runs its own collect2 program, which is a wrapper around
ld.
