Rename to OLM_LONG_DOUBLE

For some sad reason, gcc poisons LONG_DOUBLE in sreal.c. The identifier has been changed to OPENLIBM_LONG_DOUBLE

msun: signed overflow in atan2

As a component of atan2(y, x), the case of x == 1.0 is farmed out to
atan(y). The current implementation of this comparison is vulnerable
to signed integer underflow (that is, undefined behavior), and it's
performed in a somewhat more complicated way than it need be. Change
it to not be quite so cute, rather directly comparing the high/low
bits of x to the specific IEEE-754 bit pattern that encodes 1.0.

Note that while there are three different e_atan* files in the
relevant directory, only this one needs fixing. e_atan2f.c already
compares against the full bit pattern encoding 1.0f, while
e_atan2l.cuses bitwise-ands/ors/nots and so doesn't require a change.

Enable long double functions for aarch64

Per discussion in #157, it is correct to enable these for aarch64.

Cleanup `ARCH` handling, reorganize `AArch64` and `Make.inc`.

* Previously, behavior differed if the same value of `ARCH` was defined
within `Make.inc` or defined on the command line. Don't do that.

* Provide saner defaults for `ARCH` and `MARCH`, and more importantly,
allow for the proper overriding of both.

* Split `AArch64` code further away from the other `arm` code.

Avoid defining __pure2 if already defined

This gets rid of a warning on Mac OS X due to the fact that
sys/cdefs.h defines it already.

Avoid redefining endianness macros with some gcc versions

_LITTLE_ENDIAN and _BIG_ENDIAN are built-in on some platforms/versions.
Better use __ORDER_LITTLE_ENDIAN__, __ORDER_BIG_ENDIAN__ and __BYTE_ORDER__,
which are standard for gcc and clang, and define them when they are missing.
Also remove the special-case for FreeBSD, which is apprently not needed.

Rename _scan_nan() to __scan_nan().

The current tradition of openlibm is to hide all of its internal symbols
into the reserved system namespace. CloudABI has a check in place to
ensure that its C library (which contains openlibm) to not place any
unwanted symbols into the public namespace. openlibm seems to leak
_scan_nan() in there, so we'd better add an additional underscore.
