The RTEMS_BSPOPTS_* macros add defines to bspopts.h. Somewhat
oversimplified, they work similar to AC_CONFIG_HEADER/config.h.
They don't add AM_CONDITIONALS. If you really want an AM_CONDITIONAL,
you need to add it yourself.
However, you should really check, if you actually want an
exported/global define in bspopts.h or an AM_CONDITIONAL.
In most cases, you will not want either of these.
