inteltool: Fixed building of position independent executables

When building a position independent executable (PIE) EBX is used
    internally by the compiler to generate position independent address
    references so it cannot be used in the clobber list. Use the already
    existing code for the Darwin plattform for that case, too -- it'll
    preserve the EBX value.
