testsuite/libffi.call/many.c: Avoid spurious failure due to excess precision The test case testsuite/libffi.call/many.c can spuriously fail due to excess floating-point precision. Instrumenting it with some printf calls shows differences well above FLT_EPSILON. (Note when instrumenting it that multiple computations of the difference, such as one in a print and another in the conditional, may produce different results.) Rather than complicating the test suite with architecture-specific flags to avoid excess precision, just simplify the floating-point computation to avoid a dependency on potential excess precision.
