Changeset 256cbec in rtems for c/src/exec/score/cpu/hppa1.1

Patch rtems-rc-20000708-1.diff from Ralf Corsepius <corsepiu@…>
that is another small step toward multilibs:

Changes:

• Eliminate RTEMS_CHECK_CUSTOM_BSP from all configure.ins below exec/
• Add RTEMS_CHECK_CUSTOM_BSP to the multilib-disabled branch in RTEMS_ENV_RTEMSCPU to preserve the old per-BSP building scheme functional.

Notes:

• --enable-multilibs is still non-functional
• This patch should not have any influence on the old building scheme (--disable-multilib should silently fall back to the old building scheme).
• running ./bootstrap is required after applying the patch
