Only on first call to the recursive malloc lock the restore value of
exception enable fields is stored.
* libc/sys/or1k/mlock.c: Fix exception enable saving
Sorry, there was a typo in <sys/lock.h> which leads to memory corruption
since not enough space is reserved for the lock object.

* libc/sys/rtems/include/sys/lock.h (__LOCK_INIT_RECURSIVE): Use
proper type.
During libgcc build the first include search path for <...> is
"../newlib/libc/sys/rtems/include". Move all RTEMS specific header
files to "libc/sys/rtems/include" so that they can be found. Later
during libc build the header files in the previous location were somehow
present, but for libgcc build they were invisible. This change is
necessary to use <pthread.h> for the GCC thread model implementation.
