Yes the two commands (gsc followed by gcc) can (after the fix) be replaced by the single invocation of gsc:
gsc -exe -l core/ab.c -ld-options ab.a myapp.scm
Alternatively, you can completely avoid using gcc with the following sequence of commands (that also work without the recent fix):
gsc -link -l core/ab.c myapp.scm gsc -obj myapp.c gsc -obj myapp_.c gsc -exe -ld-options ab.a myapp.o myapp_.o
and yes, that is better than invoking gcc explicitly, because it will pass the correct options to gcc (or whatever C compiler Gambit was configured with).

I still don't understand. You're still compiling Gambit-generated code with gcc without the correct options.
Are you saying that now that gsc is fixed you don't need the second command, beginning with "gcc ..."?

Yes, the one that was broken and is now fixed!

So after that, you can build your app with the following commands:
gsc -link -l core/ab.c myapp.scm gcc -o myapp ab.a `gsc -e '(print (path-expand "~~lib/libgambit.a"))'` myapp_.c myapp.c
You probably shouldn't use a bare "gcc" command because it won't have the options Gambit-generated code needs for correctness. Isn't there a gsc command that does the same thing?
