[PATCH] ld: default the aarch64pe section alignment to 64K

[trcrsired]

Windows on ARM64 is increasingly run on hosts with 16K pages
(Apple Silicon, Android).  A section alignment of 4K is not a
multiple of the host page size there, so the loader (or Wine)
cannot map the image.  Default the section alignment to 64K so
that images work everywhere, including under Wine on those hosts.
