[PATCH] configure: Work around Xcode 12's ld assuming 16KB page sizes.

[Brendan Shanks]

Starting in Xcode 12, ld rounds page sizes and alignments up to 16KB
for all architectures. Passing '-segalign 0x1000' resets this back to
4KB.

I haven't noticed any ill effects from this, but it seems desirable to
keep the PAGEZERO size consistent with previous versions and other OSes.
