Indeed, “getconf PATH” returns “/bin:/usr/bin” on NixOS, which is
clearly wrong (and consequently, “command -p getconf PATH” says “command
not found”.)
I guess we should patch glibc to make it DTRT. Glibc hardwires
‘_CS_PATH’ in sysdeps/unix/confstr.h. POSIX loosely defines ‘_CS_PATH’
as “the value for the PATH environment variable that finds all standard
utilities.” [0] Unless “standard utilities” is formally defined
somewhere, we could interpret it as “the path to Coreutils” and define
it accordingly.
Thoughts?

echo(1) *is* available in $PATH in the build environment, just like all
of Coreutils.
What would you think of ‘--with-echo’?
Thanks,
Ludo’.
