Hash :8e6090d0 Message :build: use AC_CHECK_LIB over AC_HAVE_LIBRARY
AC_HAVE_LIBRARY is deprecated, see
https://www.gnu.org/software/autoconf/manual/autoconf-2.70/html_node/Obsolete-Macros.html,
and has been prior to Autoconf 2.67, which is the minimum required by
the project. It's usage also causes warnings with newer versions of autoconf:
```bash
configure.ac:319: warning: The macro `AC_HAVE_LIBRARY' is obsolete.
configure.ac:319: You should run autoupdate.
```
`AC_HAVE_LIBRARY` was introduced in #969, although it's not clear why it
was decided to revert to using an obselete macro.
