There is no substantive difference between these commands.  There are
various minor differences that probably don't matter.  Use the -v
option when invoking gcc to see precisely how it invokes the linker.

In particular, invoking the linker via the gcc driver will cause some
C++-specific operations to occur when needed, but since you aren't
using C++ in this case they won't happen.
