Log message:
gdb: update to 8.1.

local changes: use plist var for gcore.
XXX don't install gcore.1 that doesn't appear to be installed but exists
remove merged patches.

GDB 8.1 includes the following changes and enhancements:

  * Breakpoints on C++ functions are now set on all scopes by default
    ("wild" matching);

  * Support for inserting breakpoints on functions marked with C++ ABI tags;

  * Target floating-point arithmetic emulation during expression evaluation
    (requires MPFR 3.1 or later);

  * Various Python Scripting enhancements;

  * Improved Rust support; in particular, Trait objects can now be inspected
    when debugging Rust code;

  * GDB no longer makes assumptions about the type of symbols without
    debugging information to avoid producing erroneous and often confusing
    results;

  * The 'enable' and 'disable' commands now accept a range of breakpoint
    locations;

  * New 'starti' command to start the program at the first instruction;

  * New 'rbreak' command to insert a number of breakpoints via a regular
    expression pattern (requires Python);

  * The 'ptype' command now supports printing the offset and size of
    the fields in a struct;

  * The 'gcore' command now supports dumping all the memory mappings
    ('-a' command-line option);

  * New shortcuts for TUI Single-Key mode: 'i' for stepi, and 'o' for nexti;

  * GDBserver enhancements:
    ** Support for transmitting environment variables to GDBserver;
    ** Support for starting inferior processes with a specified initial
       working directory;
    ** On Unix systems, support for globbing expansion and variable
       substitution of inferior command-line arguments;

  * Various completion enhancements;

  * The command used to compile and inject code with the 'compile' command
    is now configurable;

  * New '--readnever' command-line option to speed the GDB startup when
    debugging information is not needed;

  * Support for the following new native configurations:
    ** FreeBSD/aarch64 (aarch64*-*-freebsd*);
    ** FreeBSD/arm (arm*-*-freebsd*);

  * Support for the following new targets:
    ** FreeBSD/aarch64 (aarch64*-*-freebsd*);
    ** FreeBSD/arm (arm*-*-freebsd*);
    ** OpenRISC ELF (or1k*-*-elf)

  * Removed support for the following targets and native configurations:
    ** Solaris2/x86 (i?86-*-solaris2.[0-9]);
    ** Solaris2/sparc (sparc*-*-solaris2.[0-9]);

Log message:
Sort PLIST files.

Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:

  pkglint -Cnone,PLIST -Wnone,plist-sort -r -F

Disable globally binutils, gprof, gold, gas, ld. These packages are shipped
separately in other packages.

Log message:
Prepare gdb/amd64bsd-nat.c for Debug Registers (watchpoints) on NetBSD

Define DBREG_DRX when it's undefined to:
    #define        DBREG_DRX(d,x)  ((d)->dr[(x)])

This has been copied from FreeBSD:
/usr/include/x86/reg.h:#define	DBREG_DRX(d,x)	((d)->dr[(x)])

No functional change for existing operating systems.
