Allowing unaligned sizes will allow us to allocate aligned slabs with
additional metadata in the tail without ballooning the allocation size
for large alignments.

setitimer() is obsolescent in POSIX 2008 and removed from POSIX 2024.
However, at least macOS doesn't implement the new timer_create() API, so
we still need the setitimer() fallback.

Since commit 3552b79 ("build/flags: Infrastructure to detect compiler
flag support"), this file only listed a bunch of lines like
-include obj/src/alloc.d
-include obj/src/bar.d
...
We can do that just as well from the main Makefile, and in one line too:
-include ${OBJS:.o=.d}
This lets us pull the list of all objects out of build/prelude.mk and
put it closer to where those objects are actually used.

That way if ./configure fails, make will complain about it directly.

Prior to GCC 14.1, the __builtin_riscv_pause() can cause an error if the
appropriate extension is not enabled in -march:

This lets us do more traditional out-of-tree builds like
$ ../path/to/bfs/configure
$ make
The .mk files are moved from ./config to ./build, mostly so that
./configure will auto-complete easily.
