autofs-5.1.2 - configure: add cache variable for Linux proc filesystem check
When cross-compiling, whether the /proc filesystem is available in the
build environment does not give any indication as to whether it will
be available in the execution environment.
This commit therefore adjust the AF_LINUX_PROCFS macro to use
AC_CACHE_CHECK(), so that an ac_cv_linux_procfs variable can be
preseeded in the environment to force the result of this check.
