Fix the CFI assembler test for ARM

[Daniel Jacobowitz]

configure.in has a hardcoded @function, but @ is a comment character on
ARM.  %function works on all platforms (with gas, anyway), so use that
instead.  This lets glibc detect that these ops do work on ARM.

Tested on arm-linux.

	* configure.in: Use %function instead of @function.
	* configure: Regenerated.
