Do you really want to rename foobar.xbm to foobar.xbm.gif,
or should it be to foobar.gif?

The command "basename $xbm" in that context is a no op.
This will do what you want:

  gif="$(basename $xbm xbm)gif"

But, really, this is much better:

  gif="${xbm%%xbm}gif"

Hence, with an eye to defensive programming:

#!/bin/bash
for x in *.xbm ; do
   convert "${x}" "${x%%xbm}gif"
done
