Sorry about going all officious on you over that, but it is important 
that people realize that this list is a public forum.

No. :-(

There is however an alternative...  The assembler .incbin directive.  As in:

  % cat make-section.s
  .section .data
  .incbin binary-file

  % arm-rtems4.11-as make-section.s -o make-section.o

  % arm-rtmes4.11-readelf -h make-section.o
  [...]
  Flags:                             0x5000000, Version5 EABI
  [...]

I assumed that you wanted to put the binary file into the .data section, 
but obviously you can change that by editting make-section.s.

Cheers
