musl 1.1.23 released

[Rich Felker <dalias@libc.org>]

This version merges the RISC-V (64-bit) port and new math library
implementations of log, exp, and pow. Internals of how
(non-cancellable) syscalls are performed have been overhauled so that
all code necessary to make the syscall resides in the arch-provided
header and is inlinable. In the process, bugs in the implementation of
mips and microblaze syscall mechanisms were found and fixed. Several
other bugs were fixed as well, including a potentially serious one in
the layout of static TLS for shared libraries on archs that use "TLS
variant I" layout.

A couple behaviors that were clearly undesirable but arguably mandated
by POSIX have been fixed as a result of POSIX intepretations rendering
them unnecessary.
