[PATCH] Add extra logic required to detect endianness on Solaris

[Charles Bailey <cbailey32@bloomberg.net>]

The endian detection added in 7e3dae494 isn't sufficient for the Solaris
Studio compilers. This adds some fallback logic which works for Solaris
but would also work for AIX and Linux if it were needed.
