Add UNIX large file support via compiler always-args
On 32-bit Linux and BSD, all libcs support this. Musl always enables it,
and UClibc behaves like Glibc unless it's built without large file
support (which is a terrible idea).
http://wiki.musl-libc.org/wiki/FAQ#Q:_do_i_need_to_define_LARGEFILE64_SOURCE_to_get_64bit_off_t_.3F
https://git.uclibc.org/uClibc/tree/include/features.h#n326
macOS now only ships 64-bit, so this is irrelevant there.
32-bit Windows and older versions of Bionic do not have transparent
large file support and you must use lseek64, etc there, so this won't
affect those. Newer Bionic versions behave like Glibc in theory.

Includes a linuxlike test for this.
