that is a somewhat experimental, multilib-related patch:
Changes:
* Use RTEMS_ENV_RTEMSCPU instead of RTEMS_ENV_RTEMSBSP in
configure.ins below exec/.
At the moment, RTEMS_ENV_RTEMSCPU is more or less an optical change
to emphasize that these subdirectories shall not depend on RTEMS_BSP
than a real behavioral change.
* Add AC_DEFINE_* to several aclocal/*.m4 macros to prepare
autoheader/autoconf generated targopts.h and similiar configuration
headers.
* c/src/configure.in: remove exec from cfg_subdirs if multilibs are
enabled (c/src is build per bsp, exec shall be build per cpu in c/
or from the toplevel in future, when multilibs are enabled.)
Notes:
* This patch should not have any impact on the current building scheme.
* --enable-multilib still does not work.
* running bootstrap from the toplevel directory is required.
