retire in-tree GPL dtc devicetree compiler

Now that we no longer have GCC 4.2.1 in the tree and can assume FreeBSD
is being built with a C++11 compiler available, we can use BSDL dtc
unconditionally and retire the GPL dtc.

GPL dtc now has FreeBSD CI support via Cirrus-CI to help ensure it
continues to build/work on FreeBSD and is available in the ports tree
if needed.

The copy of (copyfree licensed) libfdt that we actually use is in
sys/contrib/libfdt so the extra copy under contrib/dtc/libfdt can be
removed along with the rest of the GPL dtc.

remove GCC 4.2.1 build infrastructure

As described in Warner's email message[1] to the FreeBSD-arch mailing
list we have reached GCC 4.2.1's retirement date. At this time all
supported architectures either use in-tree Clang, or rely on external
toolchain (i.e., a contemporary GCC version from ports).

GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later
that year, in r171825. GCC has served us well, but version 4.2.1 is
obsolete and not used by default on any architecture in FreeBSD. It
does not support modern C and does not support arm64 or RISC-V.

Thanks to everyone responsible for maintaining, updating, and testing
GCC in the FreeBSD base system over the years.

So long, and thanks for all the fish.

Remove libreadline from the source tree, all consumers but gdb
has been switched to libedit long ago, libreadline was built as an
internallib for a while and kept only for gdbtui which was broken using
libreadline.

Since gdb has been mostly deorbitted in all arches, gdbtui was only installed
on arm and sparc64, given it has been removed, gdb has been switched to use
libedit, no consumers are left for libreadline. Thus this removal
