Build with 16K page sizes in mind on aarch64

By default binutils on buildroot aligns sections to 4kb boundaries, but
there are several 16k only linux distros out there now that default to
16kb pages.

With this change the elf files will have their sections aligned to 16kb
boundaries which should ensure binaries produced with the toolchain work
on most aarch64 linuxes.

package/wolfssl: security bump to version 5.6.4

[Medium] A fix was added, but still under review for completeness, for a
Bleichenbacher style attack, leading to being able to decrypt a saved
TLS connection and potentially forge a signature after probing with a
large number of trial connections. This issue is around RSA decryption
and affects static RSA cipher suites on the server side, which are not
recommended to be used and are off by default. Static RSA cipher suites
were also removed from the TLS 1.3 protocol and only present in TLS 1.2
and lower. All padding versions of RSA decrypt are affected since the
code under review is outside of the padding processing. Information
about the private keys is NOT compromised in affected code. It's
recommended to disable static RSA cipher suites and update the version
of wolfSSL used if using RSA private decryption alone outside of TLS.
