$program generates RTEMS custom/*.cfgs and config-files for gcc multilib
variants a target's gcc supports
Usage: $program [options]
Options:
--target=STRING target
--custom generate make/custom/*.cfg files
--config generate config scripts
--rtems=DIR use DIR as location of RTEMS source tree
-v, --verbose verbose
-h, --help Print this usage
--version Print version and exit
Examples:
$program --config --target=sh-rtems --rtems=/usr/src/rtems-4.5.0
Generates config scripts for all possible bare BSPs from all
valid multilib variants sh-rtems-gcc supports
$program --custom --target=sh-rtems --rtems=/usr/src/rtems-4.5.0
Generates /usr/src/rtems-4.5.0/make/custom/*.cfg files
for all possible bare BSPs from the multilib variants
sh-rtems-gcc supports
