buildsystem: use 16k max page size
By passing "-z max-page-size=16384" to the linker.
Newer Android devices use 16KB and require a recompilation with this flag. See https://developer.android.com/guide/practices/page-sizes
Neither VLC nor the contribs (used by Android) use PAGE_SIZE directly so it should be fine.
This flag is needed regardless the use of the NDK 27 or not.
