ec71044958 ld.bfd requires an explicit emulation for MIPS for ld -r.
Unlike lld, ld.bfd doesn't infer the emulation from the first object
file, but assumes its compiled in default for ld -r.

cfae6a92ac Remove an incorrect assertion from in6p_lookup_mcast_ifp().
The socket may be bound to an IPv4-mapped IPv6 address.  However, the
inp address is not relevant to the JOIN_GROUP or LEAVE_GROUP operations.

While here remove an unnecessary check for inp == NULL.

18a1e2e9b9 libregex: Implement a subset of the GNU extensions
The entire patch-set is not yet mature enough for commit, but this usable
subset is generally enough for googletest to be happy with and mostly map to
some existing concepts, so they're not as invasive.

The specific changes included here are:

- Branching in BREs with \|
- \w and \W for [[:alnum:]] and [^[:alnum:]] respectively
- \s and \S for [[:space:]] and [^[:space:]] respectively
- Additional quantifiers in BREs, \? and \+ (self-explanatory)

There's some #ifdef'd out work for allowing empty branches as a match-all.
This is a feature that's under assessment... future work will determine
how standard this behavior is and act accordingly.

9053c1a431 Allow building setmode.c on Linux/macOS
We bootstrap this file to allow compiling FreeBSD on Linux systems since
some boostrap tools use setmode(). Unfortunately, glibc's sys/stat.h
declares a non-static getumask() function (which is unimplemented!) and
that conflicts with the local getumask() function. To work around this
simply use a different name here.

338b22234b Pass the full CFLAGS to cpp for MKlib_gen.sh.
GCC's cpp was exiting immediately when it failed to find requested
includes (<ncurses_cfg.h> and <ncurses_defs.h>).  clang-cpp emitted an
error for the missing header files but continued processing the file
(thus not honoring any macros defined in the missing headers).

Arguably, the awk script is buggy since it doesn't check the return
value of the command it executes.

7393b267c6 libc: Provide sub fp(s|g)etmask() implementations for RISC-V
RISC-V doesn't support floating-point exceptions.

RISC-V Instruction Set Manual: Volume I: User-Level ISA, 11.2 Floating-Point
Control and Status Register: "As allowed by the standard, we do not support
traps on floating-point exceptions in the base ISA, but instead require
explicit checks of the flags in software. We considered adding branches
controlled directly by the contents of the floating-point accrued exception
flags, but ultimately chose to omit these instructions to keep the ISA simple."

We still need these functions, because some applications (notably Perl) call
them, but we cannot provide a meaningful implementation.

4fdb1b227c vt(4): CONS_HISTORY/CONS_CLRHIST should operate on issuing terminal
Currently the CONS_HISTORY and CONS_CLRHIST ioctls modify the state of the
active terminal instead of the terminal against which the ioctl was issued.
Because of the way vidcontrol(1) works, these are the same in most cases.
But a poorly-timed window switch can make them differ. This is reproducible
by issuing e.g. 'vidcontrol -s 2 && vidcontrol -C' to switch from vty 1 to
vty 2; teken will reset the cursor position on vty 1 but vt(4) will clear
the history buffer of vty 2, producing an interesting state of affairs.
