Description:
mysql shell arm64 prebuilt binaries is not compatible with 65536 pagesize

How to repeat:
Run 'mysqlsh -S /tmp/mysql.sock -u root -p -e "util.checkForServerUpgrade()"'
with an arm64 server which pagesize is 65536.

It will report error:
"error while loading shared libraries: libssh.so.4 ELF load command aligment not page-aligned"

Suggested fix:
add -z max-page-size=65536 to linker if needed

The problem was caused because the libssh (3rd party used by shell) was not being compiled using pagesize of 64K to make it compatible with systems with both 4K and 64K pagesize.

The library was rebuilt using the required pagesize and the problem was solved.

Added the following note to the MySQL Shell 9.3.1 release notes:
  
It was not possible to start MySQL Shell on ARM platforms if PAGE_SIZE was set to 64K. 
An error similar to the following was displayed:

mysqlsh: error while loading shared libraries: 
libssh.so.4 ELF load command aligment not page-aligned
