See 8164d511d6 ("libc/tests: Fix installation without MK_TOOLCHAIN")
for some background. Here we should really be testing MK_CLANG instead,
since that's what gates compilation of libclang_rt.
Fixes: 8164d511d6 ("libc/tests: Fix installation without MK_TOOLCHAIN")
There is some exotic conditional logic here to avoid building a
particular test if a certain UBSAN library isn't present in the
toolchain sysroot. This causes build failures for me when doing an
"installworld WITHOUT_TOOLCHAIN=", which I do frequently during tests.
I believe the problem is that SYSROOT is unset during installworld, so
the build sees the host's copy of libclang_rt.ubsan_standalone.a and
then tries to install a binary that wasn't built during buildworld. Try
to make the check a bit less fragile.

Notably:
- libc needs to #undef some of the macros from ssp/* for underlying
implementations
- ssp/* wants a __RENAME() macro (snatched more or less from NetBSD)
There's some extra hinkiness included for read(), since libc spells it
as "_read" while the rest of the world spells it "read."

This eliminates the use of non-thread-safe function in printf*() family,
and make the call locale-aware. Also, it stops obliterating the
strerror() static buffer, which aligns with the POSIX requirement that
implementations must behave as if no standard-mandated functions call
strerror().

This version of swab function simplifies the logic of swapping adjacent
bytes. Previous version of swab() used an arbitrary unrolling, which was
relevant back in the day but unnecessary for modern compilers, as if the
input size is known at compile time, they can do it automatically.
This version of swab() is inspired by musl.
A similar version can be found at: https://github.com/openbsd/src/blob/master/lib/libc/string/swab.c

Fixes: 6e6cd03c91 libc/quad: narrow list of symbols exposed on i386
Differential Revision: https://reviews.freebsd.org/D44879
I put the symbols in the wrong file (should have been
lib/libc/sys/Symbol.map), added a duplicate pdfork entry due to a botch
rebase, and there seems to be a issue with gcc13/binutils not exposing
the symbols so revert the whole thing while I debug.
This reverts commit ee632fb9eb.
List them in the symbol map rather than using the __sym_default to
expose them. This will allow later improvements in the stub
implementations in libc.so.

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.)
