Linux arm64 16kb pages (jemalloc unsupported page size)

Hello, the binary builds for linux/arm64 don't run Apple's M1/M2/M3.

attempting to run `fdbmonitor` shows that fdbserver can't start because of the statically built jemalloc is compiled w/ 4kb pages.

Here's the error:

```

This is a common problem on these machines, linux is running with 16kb pages for kernel and userland.
```
miguel@armadura vm % zgrep -i PAGE_SIZE /boot/config-$(uname -r)

CONFIG_HAVE_PAGE_SIZE_16KB=y
CONFIG_PAGE_SIZE_16KB=y
CONFIG_PAGE_SIZE_LESS_THAN_64KB=y
CONFIG_PAGE_SIZE_LESS_THAN_256KB=y

miguel@armadura vm % getconf PAGESIZE
16384
```
I have a local build of jemalloc w/ 16kb pages, but because fdb is built statically I can't use that.

Start by reproducing the failure with the arm64 fdbmonitor and fdbserver binaries on a Linux system reporting 16 KB pages. Trace how the statically linked jemalloc is selected and built, then verify that the resulting binaries start without the unsupported-page-size or bad_alloc errors. No source files or tests are named in the issue.
