My specs file has the same entry you quoted above.  The -v (not -V)
switch says:

gcc version 3.0.3 20011212 (Debian prerelease)

/usr/lib/gcc-lib/i386-linux/3.0.3/collect2 -m elf_i386
  -dynamic-linker /lib/ld-linux.so.2 -o bin/ssem
  /usr/lib/gcc-lib/i386-linux/3.0.3/../../../crt1.o
  /usr/lib/gcc-lib/i386-linux/3.0.3/../../../crti.o
  /usr/lib/gcc-lib/i386-linux/3.0.3/crtbegin.o
  -L/usr/lib/gcc-lib/i386-linux/3.0.3
  -L/usr/lib/gcc-lib/i386-linux/3.0.3/../../.. <objects>
  -static -lstdc++ -lm -lgcc_s -lgcc -lc -lgcc_s -lgcc
  /usr/lib/gcc-lib/i386-linux/3.0.3/crtend.o 
  /usr/lib/gcc-lib/i386-linux/3.0.3/../../../crtn.o

I've tried combinations of -static and -shared-libgcc and
-static-libgcc.  The -lgcc and -lgcc_s switches do not vary.  Once the
link I inserted from libgcc.a to libgcc_s.a is removed, the link fails
every time.  So, either your interpretation differs from that which
gcc performs, or gcc isn't performing as expected.
