Sounds great.

Is that a problem?  Doesn't iterating over the variable contents
as a list work, with a setting like
'DEJAGNU_SIM_BOARD_INFO={noargs 1} {gcc,stack_size 5000}' or
'DEJAGNU_SIM_BOARD_INFO={{noargs 1} {gcc,stack_size 5000}}'?

On second thought, that takes us down the road of shell
expansion problems, so maybe better go with a dedicated
separator, or a dynamically assigned one as below.

How about always having the first character be the separator,
i.e. for the above:

"/noargs 1/gcc,stack_size 5000"
