herror etc. are MISC, rcmd etc. are BSD, addrinfo functions are
POSIX.1-2001, except for IDN functionality which is GNU.

When fork fails, we can use "%s" now with system_sprintf for the errmsg
rather than a (potentially too small) buffer for the format string.
* fork.cc (fork): Use "%s" with system_printf now.
With "%C" format string, argument may convert in up to MB_LEN_MAX bytes.
Relying on sys_wcstombs to add a trailing zero here requires us to
provide a large enough buffer.
* smallprint.c (__small_vsprintf): Use MB_LEN_MAX+1 bufsize for "%C".
The previous multi-build implementation was copying the config.status from the parent
multilib directory when building the different semihosting variants. It did so because
the configuration doesn't change. However when you use a relative path to configure it
turns out that the paths inside the config.status are also relative.
To fix this, the srcdir is adjusted from the initial configuration instead of copying it.
Tested on aarch64-none-elf and arm-none-eabi.

The third argument of RtlLookupFunctionEntry actually is documented as
_Inout_opt_ for both x64 and ARM, although generic doc says _Out_ only.
* exceptions.cc (__unwind_single_frame): Initialize hist variable.
In order to avoid the year 2038 problem, define time_t to a signed
integer with at least 64-bits. The type for time_t can be forced to
long with the --enable-newlib-long-time_t configure option or with the
_USE_LONG_TIME_T system configuration define.

In case time_t is long, then the cast to long is a nop. In case time_t
is __int_least64_t, then the cast to long may truncate the value before
the division.

Newlib uses _times_r() in clock(). The problem is that the _times_r()
clock frequency is defined by sysconf(_SC_CLK_TCK). The clock frequency
of clock() is the constant CLOCKS_PER_SEC.
FreeBSD uses getrusage() for clock(). Since RTEMS has only one process,
the implementation can be simplified.

In C++, the usage of static inline functions for getchar_unlocked and
putchar_unlocked may result in error messages like
error: ‘_putchar_unlocked’ was not declared in this scope
Fix this by not using the _getchar_unlocked and _putchar_unlocked
macros in C++.

This reverts most of commit 979d467ff6.
We cannot avoid some bareword attributes until clang is fixed to
properly support __-decorated attributes; see this bug:
https://bugs.llvm.org/show_bug.cgi?id=34319
The macros in question expand to the empty string under gcc, so
only compilation under clang is affected, and since clang has the
bug, the obvious solution is to roll back the changes, and document
the issue.
