BaseTools: Add GCC flags to Basetool build.
BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=1764
Some compiler flags restrict the compiler from making
arbitrary decisions while handling undefined C/C++ behaviors.
Therefore they can be used to fix some issues caused by undefined behavior.
For example, for GCC, the following flags are available:
-fno-delete-null-pointer-checks tells
the compiler NOT to assume that null pointer deference does not exist.
-fwrapv tells the compiler that signed overflow always wraps.
This patch is going to add these 2 build options to
BaseTool GCC build option.
