Improve the portability of grep patterns in configure.ac
...
The configure.ac script uses backslash plus in its grep patterns to
match one or more occurrences. This is a GNU grep extension to the
Basic Regular Expressions syntax that fails on systems with a more
traditional grep. This changes fixes grep patterns that use backslash
plus to use a star instead.

Always use pthread_equal to compare thread IDs

This change replaces direct comparisons of Pthread thread IDs with
calls to pthread_equal. Directly comparing thread IDs is neither

Change the default page size to 64KiB on Aarch64 Linux
...
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.

Define malloc_{write,read}_fd as non-inline global functions
