distrib/sets/lists: Add a blank comment line between RCS id and body.

This serves as a buffer between RCS id changes and other changes to
the set lists, in an attempt to reduce the pain of merge conflicts
around mass set list changes.

No functional change intended.

branches: 1.10.40;
Mark all _pic.a archive files with the 'picinstall' flag.

This fixes checkflist with MKPICINSTALL=no.

ok christos@.

Add a new "debug" set that gets built when ${MKDEBUG} is set. On evbarm:
-rw-r--r-- 1 root src 35806068 Jan 16 10:47 base.tgz
-rw-r--r-- 1 root src 57374069 Jan 16 10:48 comp.tgz
-rw-r--r-- 1 root src 101286193 Jan 16 10:49 debug.tgz
...
This allows always building the debugging code and libraries but not
installing it (although now it is placed in the default sets if ${MKDEBUG}
is set

branches: 1.8.6; 1.8.12;
libm68k debug

Add a bunch of .debug entries, determined by inspecting the equivalent
comp lists.
Inspired by PR 39370

branches: 1.6.30; 1.6.34;
Move the lib<foo>.so entry (link) from comp to base, so that
applications on systems without the `comp' set installed can
dlopen() a library without supplying the major number.

reformat whitespace

Fix placement of lib{arm,m68k}_pic.a, fwiw.

Back out change that made libpthread per-platform. It is *intentional*
that the build fails on platforms which do not yet have libpthread support.

Not all ports/archs have pthread support. So split this up by the proper arch's
for determining which ones get the libraries. Tested on dreamcast, macppc
and i386 builds to cover non builds, ad and md mods

branches: 1.1.2;
Added support for ad.${machine_cpu}.shl listfiles. These list
architecture-dependent files that are present when shared libraries are in use.
