fix fesetenv(FE_DFL_ENV) on i386
the default fenv was not set up properly, in particular the tag word that indicates the contents of the x87 registers was set to 0 (used) instead of 0xffff (empty) this could cause random crashes after setting the default fenv because it corrupted the fpu stack and then any float computation gives NaN result breaking the program logic (usually after a float to integer conversion).
