Android NDK r19c (build 5345600)
Fix MacOSX 10.10 SDK build

Apparently _SC_PHYS_PAGES was added in the 10.11 SDK, but even though
HW_PHYSMEM isn't in the manpage, it exists in all the SDKs we care
about. (It is capped at 32-bits however, since HW_PHYSMEM64 is not
available)

Bug: 36130900
Test: build on Mac 10.13
Test: check headers in 10.10 SDK
