posix: Change pthread_once to be SMP safe.

Change pthread_once from using disabled pre-emption to using a
pthread mutex making it SMP safe. GCC using a posix threading
model uses pthread_once.

The pthread mutex requires at least 1 mutex is configured so
confdefs.h has been updated to account for the internal
mutex.

4	* @brief Configuration Table Template that will be Instantiated
5	* by an Application
6	*
7	* This include file contains the configuration table template that will
8	* be instantiated by an application based on the setting of a number
9	* of macros. The macros are documented in the Configuring a System
10	* chapter of the Classic API User's Guide
11	*
12	* The model is to estimate the memory required for each configured item
13	* and sum those estimates. The estimate can be too high or too low for
14	* a variety of reasons:
15	*
16	* Reasons estimate is too high:
17	* + FP contexts (not all tasks are FP)
18	*
19	* Reasons estimate is too low:
20	* + stacks greater than minimum size
21	* + messages
22	* + application must account for device driver resources
23	* + application must account for add-on library resource requirements
24	*
25	* NOTE: Eventually this may be able to take into account some of
26	* the above. This procedure has evolved from just enough to
27	* support the RTEMS Test Suites into something that can be
28	* used remarkably reliably by most applications.

574	* The following applies to the data space requirements
575	* of the Priority Scheduler.
576	*
577	* By reducing the number of priorities in a system,
578	* the amount of RAM required by RTEMS can be significantly
579	* reduced. RTEMS allocates a Chain_Control structure per
580	* priority and this structure contains 3 pointers. So
581	* the default is (256 * 12) = 3K on 32-bit architectures.
582	*
583	* This must be one less than a power of 2 between
584	* 4 and 256. Valid values along with the application
585	* priority levels and memory saved when pointers are
586	* 32-bits in size are:
587	*
588	* + 3, 2 application priorities, 3024 bytes saved
589	* + 7, 5 application priorities, 2976 bytes saved
590	* + 15, 13 application priorities, 2880 bytes saved
591	* + 31, 29 application priorities, 2688 bytes saved
592	* + 63, 61 application priorities, 2304 bytes saved
593	* + 127, 125 application priorities, 1536 bytes saved
594	* + 255, 253 application priorities, 0 bytes saved
