And additionally, the libm-test-ulps are not there to help every
compilation pass.  They are there to ensure quality.  If a compiler
generates code which makes a test fail (while compiled differently it
works) this means that either the compiler or the code need work.  On
x86 the math library simply depends on some functions being inlined
and this is what -Os prevents.
