Mike Karels d5d97bed4a arm64 lib32: prepare arm64 headers to redirect to arm
In order to compile lib32 libraries and other 32-bit code on arm64,
<machine/foo.h> needs to be redirected to an arm header rather
than arm64 when building with -m32.  Ifdef the arm64 headers that
are installed in /usr/include/machine and used by user-level software
(including references from /usr/include/*.h) so that if __arm__ is
defined when including the arm64 version, <arm/foo.h> is included
rather than using the rest of the file's contents.  Some arm headers
had no arm64 equivalent; headers were added just to do the redirection.
These files use #error if __arm__ is not defined to guard against
confusion.  Also add an include/arm Makefile, and modify Makefiles
as needed to install everything, including the arm files in
/usr/include/arm.  fenv.h comes from lib/msun/arm/fenv.h.

The new arm64 headers are:
    acle-compat.h
    cpuinfo.h
    sysreg.h
