Change the default page size to 64KiB on Aarch64 Linux

Browse source 
This updates the configuration script to set the default page size to
64KiB on Aarch64 Linux.  This is motivated by compatibility as a build
configured for a 64KiB page will work on kernels that use the smaller
4KiB or 16KiB pages, whereas the reverse is not true.

To make the configured page size setting more visible, the script now
displays the page size when printing the configuration results.

Users that want to override the page size in to choose a smaller value
can still do so with the --with-lg-pagesize configuration option.
