[GDB/ARM] Expect prompt after no FPU warning

  Hi,

The expected output for info float when the ARM target has no FPU does
not include the GDB prompt. This occasionally cause a test failure in
the following "finish" test when the prompt happens after the test has been
marked as PASSed, since it does not match the expected output.

This patch adds the GDB prompt to the expected output of the no FPU
regular expression.

ChangeLog entry is as follows:

*** gdb/testsuite/ChangeLog ***

2017-04-27  Thomas Preud'homme  <thomas.preudhomme@arm.com>

	* gdb.base/float.exp (info float): Expect GDB prompt for ARM
	targets without FPU.

Testing: test PASSes with that patch.

Is this ok for master branch?

Best regards,

Thomas

Remove " (info float)".

The fix is right but it can be applied to all archs which may not have
FPU.  If you search "N floating.point info", you can find multiple hits.
$gdb_prompt is needed for all of them.

Err yes sorry, I didn't add it because I only tested on ARM. I'll update the 
patch. Thanks!
