Two noteworthy changes:
- $@ went missing, I've occasionally abused that to add extra argument
to objdump.
- you removed the glob after FUNC, I had that so that .cold and
.constprop etc.. variants of the function also show up.
I don't suppose either one are super important, but esp. that latter one
has been convenient.
