Retire obsolete GDB 6.1.1

2020-12-15T17:44:19+00:00

GDB 6.1.1 was released in June 2004 and is long obsolete. It does not
support all of the architectures that FreeBSD does, and imposes
limitations on the FreeBSD kernel build, such as the continued use of
DWARF2 debugging information.

It was kept (in /usr/libexec/) only for use by crashinfo(8), which
extracts some basic information from a kernel core dump after a crash.
Crashinfo already prefers gdb from port/package if installed.

Future work may add kernel debug support to LLDB or find another path
for crashinfo's needs, but in any case we do not want to ship the
excessively outdated GDB in FreeBSD 13.

Disable sbrk() use in GNU tools.

2018-09-21T17:44:05+00:00

We're studing the possibility of deprecating sbrk().  To make it easier
we're removing unnecessicary uses in the base system.  None of these
tools require sbrk(), but they agressively prefer it for no good reason.

Add a new knob WITH_DEBUG_FILES to control the building of standalone

2013-06-07T21:40:02+00:00

debug files for userland programs and libraries.  The "-g" debug flag
is automatically applied when WITH_DEBUG_FILES is set.

The debug files are now named ${prog}.debug and ${shlib}.debug for
consistency with other systems and documentation.  In addition they are
installed under /usr/lib/debug, to simplify the process of installing
them if needed after a crash.  Users of bsd.{prog,lib}.mk outside of the
base system place the standalone debug files in a .debug subdirectory.
GDB automatically searches both of these directories for standalone
debug files.

Thanks to everyone who contributed changes, review, and testing during
development.

Fix typo. Not a win in terms of functionality but in terms of completeness.

Note two shortcomings of GDB on MIPS that should be addressed.
