[mainline/4.0?] Fix 32-bit ieee tests on Linux/x86-64

[Andreas Jaeger <aj at suse dot de>]

The 32-bit x86 tests in gcc.c-torture/execute/ieee always set the
compiler flag "-ffloat-store".  If we run these tests with a multilib
GCC for Linux/x86-64 in 32-bit mode, a number of tests fail since
"-ffloat-store" is not passed to the compiler.

The following patch fixes this (tested with running the testsuite with
and without "-m32") and adds the parameter for the 32-bit multilib.

Ok to commit?

This is not a regression - but I'd prefer to see this in 4.0 as well
so that the testresults look sane.  Mark, what do you think?
