Is there a good reason for providing this list via a command line switch 
as opposed to say using a suitably customised linker script ?  (Possibly 
with an extended grammar for input section selection).

What is the real purpose of this feature ?  Ie do you know why it has 
been requested ?  The implication of the example you have given is that 
the user wants to put certain name-mangled functions at the start of the 
.text section, but why ?

(I suspect that the user's problem could be solved without modifying the 
linker by using gcc's "section" function attribute instead...)

How do you specify that the named section is intended to go *after* the 
other sections that start with the same prefix ?
