Note--if the linker is being invoked indirectly, via a compiler driver (e.g.
mand line options should be prefixed by
driver) like this:
gcc -Wl,--startgroup foo.o bar.o -Wl,--endgroup
This is important, because otherwise the compiler driver program may silently drop the linker options,
resulting in a bad link.
Here is a table of the generic command line switches accepted by the GNU linker:
