[PATCH v2 0/2] nolibc: Add fallocate()

[Daniel Palmer]

While poking around with my "static PIE for nommu" series I found
I needed fallocate(). Implementing it turned out a bit more
interesting than I thought it would be due to how the offset and
size need to be passed on 32bit machines.

I have ran the tests on m68k, arm, arm64, riscv[32|64], x86_64,
i386, x32 (v2: + lots of mips, ppc..) . I probably missed something,
maybe there is a better way to do this. Maybe it can't actually
pass an offset or size >4GB on x32? (v2: I think this is good now)

v2:
 - Addressed Thomas' comments
 - Trial and error'd a test for the arguments being passed correctly.
   Hopefully someone smarter than I am can tell if it actually works.
