As pointed out by Kang-Che Sung and verified by Jody Bruchon, the "%m"
format placeholder is really not in any open standard.

The previous iteration of these changes tried to replace the "%m" by
explicit strerror(errno) manually, but as Kang-Che Sung indicated, this
is not very elegant.

Sadly, we cannot use bb_perror_msg() here because the functionality of
that helper is very different (and lacks support for ash's TRACE).

Happily, I could easily follow bb_perror_msg()'s example and introduce
a new helper in ash's source code.

Johannes Schindelin (2):
  ash: introduce ash_perror_msg_and_raise_error()
  ash: avoid GLIBC'ism %m
