The PKG_CHECK_VAR() macro is not available on versions of pkgconfig before 0.28, which breaks configure on RHEL-7, Ubuntu 16, and others. This patch copies the definition generated by newer versions of autoconf to be used for compatibility with older versions. Tested with automake 1.14.1-2ubuntu1 and autoconf 2.69-6 on Ubuntu 14.
