Added options to enable/disable components, added checking for more prereqs

BUILD_MA_LINES_PLUGIN and BUILD_LINES2INSNS options control if "ma_lines"
and "lines2insns" are to be built. Both are "on" by default.

Added checking for more prerequisites for these components: GCC plugin
support, C++11 support, etc.

Raised the minimum required CMake version to 2.8.10
(needed to have CMAKE_C_COMPILER_VERSION).
