I had to fix some files in order to get my system to build after
/sys/arch/i386/include/endian.h was changed to use u_int{16,32}_t
in the [hn]to[nh][sl]() macros.  It is now necessary to #include
<sys/types.h> before <machine/endian.h> on the i386.  Some of the
affected files (the ones I remember) were:

src/lib/libc/stdlib/strtod.c
src/lib/libc/stdlib/strtoq.c
src/lib/libm/src/math_private.h

Should <machine/endian.h> depend on <sys/types.h> in this manner?
If that's valid, then I can send-pr the changes I had to make.
