PR13802, referred common symbol not UNDefined

[Alan Modra]

It looks like this one was previously just swept under the rug.  Prior
to git commit c4b126b87a6c, the arm backend emitted an absolute
dynamic symbol "foo" with value zero for what was originally a common
symbol.  That was just wrong.

The patch also removes an xfail for bfin-linux-uclibc.

	PR 13802
	* testsuite/ld-elf/comm-data.exp: Don't xfail arm or bfin-linux.
