[PATCH] libgloss: sparc_leon: workaround newer newlib pthread APIs

[Mike Frysinger]

Fix a compile error due to duplicate pthreads types:
.../libgloss/sparc_leon/mutex.c:50:8: error: conflicting types for ‘pthread_mutex_t’; have ‘struct pthread_mutex’
   50 |      } pthread_mutex_t;
In file included from .../newlib/libc/include/sys/types.h:221,
                 from .../libgloss/sparc_leon/mutex.c:26:
.../newlib/libc/include/sys/_pthreadtypes.h:154:20: note: previous declaration of ‘pthread_mutex_t’ with type ‘pthread_mutex_t’ {aka ‘long unsigned int’}
  154 | typedef __uint32_t pthread_mutex_t;      /* identify a mutex */

.../libgloss/sparc_leon/mutex.c:57:8: error: conflicting types for ‘pthread_mutexattr_t’; have ‘struct <anonymous>’
   57 |      } pthread_mutexattr_t;
../newlib/libc/include/sys/_pthreadtypes.h:169:3: note: previous declaration of ‘pthread_mutexattr_t’ with type ‘pthread_mutexattr_t’
  169 | } pthread_mutexattr_t;
