[PATCH, 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
