Merge #460: [build] Update ax_jni_include_dir.m4 macro

Browse Source 
e7daa9b [build] Tweak JNI macro to warn instead of error for JNI not found. (Karl-Johan Alm)
5b22977 [build] Update ax_jni_include_dir.m4 macro to deal with recent versions of macOS (Karl-Johan Alm)

Pull request description:

  Prior to this patch, this macro fails to find a working directory for the JNI headers, and results in compile failure when doing
  ```
  ./configure --enable-experimental --enable-module-ecdh --enable-jni
  ```
  on more recent macOS versions. The relevant commit upstream is [here](http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=commit;h=ab23d25b1f1ae544fffdaa0a94a794798695c672) from the [GNU.org page for the macro](https://www.gnu.org/software/autoconf-archive/ax_jni_include_dir.html). The original (identical to the version in this commit) is [here](http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_jni_include_dir.m4).

  The compile failure:
  ```Bash
  $ make
  gcc -I. -g -O2 -Wall -Wextra -Wno-unused-function -c src/gen_context.c -o gen_context.o
  gcc gen_context.o -o gen_context
  ./gen_context
