I'm really confused: I have
        (i) a TAI-10 system clock, AND
        (ii) a right timezone
What will happen if I diet compile
        (i) *with* flag-clockistai, and
        (ii) *without* flag-tzisright ?
This means lying to skalibs about the tz, but given that the diet libc
is broken will the errors somehow cancel out? (Wishfull thinking...)
If not, it seems better to give up on dietlibc re skalibs et al. But
musl is not up to it... :(

An emergency is when I need all the help I can get, in particular a
shell with history and tab completion, and colors. ash just doesn't cut

I used it to compile e2fsprogs (again, to my initramfs).
