Saleem Abdulrasool b720a6bab7 ARM: remove ancient -arm-tail-calls option 
This option is from 2010, designed to work around a linker issue on Darwin for
ARM.  According to grosbach this is no longer an issue and this option can
safely be removed.

use them anyway, and they interfere with O0 CodeGen).
