I finally created a generic-sim.exp file that reads environment files
and have used it for some of my GCC testing. Here is what I created, it
looks for DEJAGNU_SIM, DEJAGNU_SIM_MULTILIB_OPTIONS, DEJAGNU_SIM_GCC,
DEJAGNU_SIM_INCLUDE_FLAGS, DEJAGNU_SIM_LINK_FLAGS,
DEJAGNU_SIM_LDSCRIPT, and DEJAGNU_SIM_BOARD_INFO. This seems to cover
most of what I saw used in the various baseboards.
DEJAGNU_SIM_BOARD_INFO is in tcl list format like:
DEJAGNU_SIM_BOARD_INFO="{noargs 1} {gcc,stack_size 5000}"
which results in:
set_board_info noargs 1
set_board_info gcc,stack_size 5000
