libraries become available for powerpc CPU architectures, they can be
added before the "nothing for other powerpc yet" case. Similar for the

I reorganized the libclang_rt Makefile in e77a1bb275 to make it more

This caused almost no libclang_rt libraries to be built for powerpc64
and powerpc64le.

TCP_USE_DDP is a kernel-only macro, so we must exclude it in
libsysdecode to avoid breaking the build.
Fixes: 3d0a736796 ("tcp: Add a new kernel-only TCP_USE_DDP [...]")
The (optional) third argument of fcntl is sometimes a pointer so change
the type to intptr_t. Update the libc-internal defintion (actually used
by libthr) to take a fixed intptr_t argument rather than pretending it's
a variadic function. (That worked because all supported architectures
pass variadic arguments as though the function was declared with those
types. In CheriBSD that changes because variadic arguments are passed
via a bounded array.)

Undo the 80-bit "stub" implementation of the 128-bit long double
tgammal(3) function. The latest (as of Feb 2024) version of the
src/contrib/arm-optimised-routines library includes a standalone,
full 128-bit replacement. This needs a small bit of wrapping to
fit it in, but is otherwise a drop-in replacement.
Testing this is hard, as most maths packages blow up as soon as
their 80-bit floating-point capability is exceeded. With 128-bit
tgammal(), this is easy to do, and this is the range that needs to
be checked the most carefully. Using my copy of Maple, I was able
to check that the output was within a few ULP of the correct answer,
right up to the point of 128-bit over- and underflow. Additionally,
the results are no worse, and indeed better than the 80-bit version.
Steve Kargl sent me his libm testing code, which I used to verify
that the excpetions for certain key values were correct. Tested in
this case were +-Inf, +-NaN, +-1 and +-0.

These provide standard APIs, but are implemented using another system

The old timezone(3) function has long since been obsolete and has a
fatally flawed interface. Retain this function for compatibility
purposes, but shift to providing the offset from UTC in the timezone
variable, whether or not the timezone observes summer time in the
'daylight' variable. Document the tzname variable that's already been
set. Also make _tztab() static. It's not used in libc (or anywhere in
the tree) and it's not exported as a public dynamic symbol.

Unlike other architectures, i386 only defined syscall() and not
_syscall() or __sys_syscall(). The syscall() function then invoked the
desired system call directly rather than invoking syscall(2). Keep the
latter as it's marginally more efficent, but also create the
conventional _syscall() and __sys_syscall() stubs.
This avoids the need to special case syscall(2) in the symbol list
generation in libsys.
