Since Ada was originally targeted at the Embedded System market where
you typically have no OS to depend on, most vendors will provide you
with a Run-Time-Kernel (RTK) which supports what would otherwise be "OS
Calls" to support task scheduling, etc. (That is, if you are looking at
a compiler that bills itself as targeted for embedded systems. There are
a number to choose from.) 

There is a RTK floating about called "RTEMS" which was originally
written in Ada and provides the support needed for an embedded target.
You may want to investigate RTEMS as one way to go. Also, check with the
major venders (Aonix, Ada Core Technologies, Green Hills, etc.) and
inquire about their support for your target of interest. For most
popular processors, you can very easily find one or more Ada compilers
that will target to the bare hardware.
