perror: work around FreeBSD bug

POSIX requires that 'errno = 0; perror ("")' print the same message
as strerror(0), but this failed if we were replacing strerror to work
around the FreeBSD bug of treating 0 as a failure.

The goal here is to _not_ replace perror on glibc, even though
strerror_r has to be replaced, because the strerror_r replacement is
only for the sake of correcting the signature rather than working
around bugs in the handling of any particular errnum value.  Recall
that $gl_cv_func_strerror_r_works is only set if the POSIX signature
was detected in the first place.

is broken.  Move AC_LIBOBJ...
