Unfortunately the -z max-page-size option is poorly documented.  What
do we think it should mean?  For the GNU linker, the option has two
effects: 1) set the value for CONSTANT (MAXPAGESIZE) in a linker
script; 2) set the default value for page alignment of program
headers.

In practice it sets the minimum page size to use for a demand paged
executable.  You seem to be suggesting that it should also set a
maximum page size, in effect suggesting that it should be the exact
page size to use.  Is that we want?
