That seems silly.  Under what circumstances would you want to compile
with optimization but link without or vice versa?  Seems to me that a
-O on the compiler link command line should pass through to the
linker, though perhaps only for n>1.

And perhaps there should be an -flink-gc option that would imply
-ffunction-sections -fdata-sections -fvtable-gc -Wl,--gc-sections.
