Subject: roadmap: describe glibc commands.

Some glibc commands are irrelevant because they're for functionality
that is excluded from musl (mtrace, rpc*, localedef, iconvconfig, nscd).
getconf and catchsegv look like candidates for the development toolchain;
locale and iconv were already triaged.
getent is pretty lame, but it and the timezone stuff (tzselect zic
zdump) are the only new possibly interesting commands.

-<p>Of those, musl libc only implements ldd. I have no idea which of the rest

+<p>Of those, musl libc only implements ldd.</p>
+<p>catchsegv is a rudimentary debugger, probably out of scope for toybox.</p>
+<p>iconv has been <a href="#susv4">previously discussed</a>.</p>
+<p>iconvconfig is only relevant if iconv is user-configurable; musl uses a
+non-configurable iconv.</p>
+<p>getconf is a posix utility which displays several variables from 
+unistd.h; it probably belongs in the development toolchain.</p>
+<p>getent handles retrieving entries from passwd-style databases, 
+in a rather lame way.</p>
+<p>locale was discussed under <a href=#susv4>posix</a>.
+localedef compiles locale definitions, which musl currently does not use.</p>
+
+<p>mtrace is a perl script to use the malloc debugging that glibc has built-in;
+this is not relevant for musl, and would necessarily vary with libc. </p>
+<p>nscd is a name service caching daemon, which is not yet relevant for musl.
+rpcinfo and rpcent are related to rpc, which musl does not include.</p>
+
+<p>tzselect outputs a TZ variable correponding to user input. 
+The documentation does not indicate how to use it in a script, but it seems
+that Debian may have done so.
+zdump prints current time in each of several timezones, optionally
+outputting a great deal of extra information about each timezone.
+zic converts a description of a timezone to a file in the tz format.</p>
+
+<p>So this leaves the following interesting commands:</p>
