Complement commit ae52f4830604 ("Add MIPS r3 and r5 support.") and get
changes for config.sub to recognize MIPS CPU patterns for the R3 and R5
ISA levels, used by GAS to set defaults in gas/configure.ac. Oddly, R6
ISA support has been correctly added already.

The mingw build fails with Readline 8.1, because sigprocmask is called
unconditionally. This patch adds the missing check for
HAVE_POSIX_SIGNALS.
I reported this upstream here:

This imports readline 8.1. I did this via various hackery in a
readline git repository to make a version of readline identical to
gdb's, then did a git merge.

This updates readline/README to mention the current patchlevel, and

Christian's recent patches to gnulib made me realize that readline
should be changed to use AC_CONFIG_MACRO_DIRS (ACLOCAL_AMFLAGS is
deprecated) and that it can put the automake options into
configure.ac. I also added no-define to the automake options. This
doesn't matter much (we don't generate a config.h here), but gnulib
does it, and it does make configure slightly smaller.

* configure.ac: Use AC_CONFIG_MACRO_DIRS. Pass options to
AM_INIT_AUTOMAKE.

readline turns out to be a bit of a stumbling block for the project to
move gdbsupport (and then gdbserver) to the top-level.
The issue is that readline headers are intended to be included with
names like "readline/readline.h". To support this, gdb effectively
adds a -I option pointing to the top-level source directory -- but,
importantly, this option is not used when the system readline is used.
For gdbsupport, a -I option like this would always be needed, but that
in turn would break the system readline case. This was PR build/17077,
fixed in commit a8a5dbcab8df0b3a9e04745d4fe8d64740acb323.
Previously, we had discussed this on the gdb-patches list in terms of
removing readline from the tree
https://sourceware.org/ml/gdb-patches/2019-09/msg00317.html
However, Eli expressed some concerns, and Joel did as well (off-list).
Given those concerns, and the fact that a patch-free local readline is
relatively new in gdb (it was locally patched for years), I changed my
mind and decided to handle this situation by moving the readline
sources down a level.
That is, upstream readline is now in readline/readline, and the
top-level readline directory just contains the minimal configury
needed to build that.
This fixes the problem because, when gdb unconditionally adds a
-I$(top_srcdir), this will not find readline headers. A separate -I
will be needed instead, which is exactly what's needed for
--with-system-readline.
