FreeBSD autotools changes (#142)
* Updates to allow autotools builds on recent FreeBSD
* Switches the default C compiler to cc from gcc
(this may need a version string check if we want to support
FreeBSD 9 and earlier. FreeBSD 10 was released in 2014)
* Makes the default C++ compiler c++ (no previous setting)
* Both of these resolve to Clang on FreeBSD 10+
* Added a note about flang being unsuitable on FreeBSD
(the port uses an ancient build of flang that lacks Fortran
2003 support)
* Autotools only - CMake appears to use different CPP flags
which cause compilation errors
* Adds a RELEASE.txt note for new FreeBSD autotools changes
