On a typical system running systemd, the telinit in PATH is very likely to be a symlink
to systemctl. Setting TELINIT to this may result in an infinite recursion if telinit is called
and sd_booted() == 0. This may commonly occur in a chroot environment.

[zj:
The path was originally hardcoded as "/lib/upstart/telinit", but was made configurable without
changing the default in 4ad61fd180. Then the default was
changed to `/lib/sysvinit/telinit` in abaaabf40a. Then it
started being autodetected when meson support was added in
5c23128dab. This patch restores the behaviour that was
implemented in configure.ac at the time of its removal.]
This reverts commit 4f5e972279.
Building with gperf 3.0 works just fine; we had an autoconf check to
determine the correct data types, and this check was ported to meson.
test_readlink_and_make_absolute switches to a temp directory, and then
removes it.
test_get_files_in_directory calls opendir(".") from a directory that has
been removed from the filesystem.
This call sequence triggers a bug in Gentoo's sandbox library. This
library attempts to resolve the "." to an absolute path, and aborts when
it ultimately fails to do so.
Re-ordering the calls works around the issue until the sandbox library
can be fixed to more gracefully deal with this.

gperf-3.1 generates lookup functions that take a size_t length
parameter instead of unsigned int. Test for this at configure time.

Depending on how binutils was configured and the --enable-fast-install
configure option, the test binary might be called either name.
