3f42b0f38d Ran bootstrap and bootstrap -p scripts. 
Added definitions of STDOUT_FILENO and STDERR_FILENO in bsp.h.

Removed the tools subdirectory in c/src/lib/libbsp/patmos/pasim. The tools subdirectory provide additional tools that aid in using the target board, namely a script to automate running the RTEMS Test Suites on the BSP.

For functions boot_card and abort_trap, included the __attribute__ ((used)) attribute in the file headers, and removed the attribute in the actual function declaration.

a2990ea7b8 Added the linkcmds.base file to the commit. 
Fixed some hard_reset code, mostly related to the assembly nomenclature.

In CPU_Context_Switch and CPU_Context_Restore routines, added instruction to reset r0, and spilled cache in CPU_Context_Restore.

Reviewed the CPU_Context_Initialize routine.

Removed the CPU_Minimum_Stack structure from the Patmos CPU, and reviewed all the Patmos context areas (general, floating point, interrupt). Removed structure CPU_Trap_table_entry, macro _CPU_Context_Initialization_at_thread_begin. Adapted the _CPU_Fatal_halt macro to Patmos.
