Patch to fix gfortran.dg/integer_exponentiation_3.F90 test

[Steve Ellcey]

The integer_exponentiation_3.F90 test is failing on the hppa64-*-*
target.  It looks like it needs to do an ATEST (approximate test) for
0.2**9 instead of an exact test.  This is already being done for other
comparisions in the same test program.

Tested on hppa64-hp-hpux11.11.  OK for checkin?

	* gfortran.dg/integer_exponentiation_3.F90: Use approx. check.
