	All IEEE tests in the execute/ieee directory should be tested this
way.  The tests are meant to test IEEE conformance, so they should set the
compiler into IEEE-compliant mode for the architecture.

	execute/ieee/ieee.exp already sets additional_flags to
[target_info ieee_multilib_flags], but I don't know how to add
"-ffloat-store" to the ieee_multilib_flags for rs6000-*-aix* and
powerpc-*-aix* triplets.  No explicit IEEE multilib is created for that
target, but the -ffloat-store flag should be passed to the compiler when
running tests in that subdirectory.
