b6cd89849e Don't let tgammal() modify signgam. Only lgamma*() should modify it. 
Letting tgammal() modify signgam has two disadvantages:

- It breaks valid code that assumes that the value of signgam is not
  clobbered by calls to tgammal().
- It makes this function depend on the presence of signgam. signgam is
  an X/Open System Interface. It is not part of the C standard.

Portability fixes

78f622e84a Use endianness definitions provided by GCC or Clang if available. 
Instead of using all sorts of operating system specific constructs, we
can just query the compiler which byte order is being used. This has the
advantage that the code builds on new platforms without any tweaks.

9a48c87386 Don't attempt to pull in <sys/cdefs.h> directly. 
<sys/cdefs.h> is not a standard header. Instead, we'd better pull in a
common header like <stdio.h>. It is very likely that such a header
already provides the necessary bits.

f9fd21c96f Don't define __ISO_C_VISIBLE unconditionally. 
__ISO_C_VISIBLE is already defined on FreeBSD. By default, it has a
value of 2011. This causes a lot of compiler warnings.

f835657bd8 Remove checks against header guards. 
It seems that this header conditionally tests whether <complex.h> is
included, as the 'complex' keyword is otherwise not available. This
version of math_private.h includes <complex.h> unconditionally, so there
is no need to test against this.

71f60ec632 Prevent the use of deprecated or internal functions if possible. 
The finite() function has been superseded by isfinite(). There is also
no need to use scalb(), as the exponent is also an integer value. We can
simply use scalbn().

There is also no need to use __isnanf(). The values passed are
guaranteed to be of type float, meaning we can safely use the standard
isnan().

7df63d456e Remove unneeded tests for <sys/cdefs.h>. 
This test is also present in FreeBSD's <machine/ieeefp.h>. For FreeBSD
it makes sense, but for a portable math library, we cannot assume that
the system has a header file like <sys/cdefs.h> and that it uses a
common header guard.

9101f61238 Added Travis test script 
This builds Openlibm on the Travis build host (x86) and also
cross-compiles to ARM.

Note: the tests currently fail on ARM, as noted in
https://github.com/JuliaLang/openlibm/issues/18
