Subject: Support building on FreeBSD

SetFlags.cmake

	Add -lexecinfo to linker flags for FreeBSD to resolve backtrace()

lib/sqlite/CMakeLists.txt

	Define _XOPEN_SOURCE to 600 instead of __POSIX_VISIBLE to 200112 for
	POSIX 1-2001 support. For POSIX standards, the _XOPEN_SOURCE define
	controls the eventual value of __POSIX_VISIBLE. _XOPEN_SOURCE is defined
	to 500 in sqlite.c if not already defined, which sets up _POSIX_C_SOURCE
	and __POSIX_VISIBLE to the 199506 for POSIX.1c

lib/tolua++/CMakeLists.txt
src/CMakeLists.txt

	Add /usr/local/lib to the library search path for FreeBSD builds

src/OSSupport/Errors.cpp

	Correct the strerror_r() implementation determination to check whether
	_GNU_SOURCE is defined, not what it evaluates to
