For what it's worth:
Although I can run ksh93 with a patched musl (see the g_hack branch* if you're curious), it crashes on executing any external command.
I have yet to track down whether this is an issue with the patches, UB, or ABI incompatability in musl.

>From the LFS list, I'm not sure about DejaGnu, texinfo, tcl (I think some versions work, but don't know about all of them), sysklogd, expect, or systemd (I think LFS wants that for udev); sysvinit works as expected apart from who/related utils, plus previous runlevel changes aren't known (utmp).
Beyond LFS, I'd suggest:
-Xorg, with Intel/Radeon/Nouveau/modesetting/vesa/fbdev drivers.
These *should* work at present, as well as GTK2.
-Python is too widely used on Linux for incompatability to be easily overlooked.  I know sabotage builds it, are patches required?
-A full LAMP stack or similar (LAMP currently means upstreaming anything needed for Apache/PHP to build, and getting MySQL or MariaDB working...PostgreSQL is the DB I'd want, though ;))

Longer-term, making sure Wine, Java, Qt, GTK3, and Webkit work is probably going to be important for relevance. I don't really like most of them, but that's where the action is.
