gpp-aioptool: add -fcommon to fix build with gcc10

Fix:
| ...ld: src/aiop_logger.o:(.bss+0x0): multiple definition of `_debug_flag'; src/aiop_tool.o:(.bss+0x0): first defined here
| ...ld: src/aiop_logger.o:(.bss+0x2): multiple definition of `_verbose_flag'; src/aiop_tool.o:(.bss+0x2): first defined here

+Subject: [PATCH] add -fcommon to fix gcc 10 build issue
+
+Fix:
+| ...ld: src/aiop_logger.o:(.bss+0x0): multiple definition of `_debug_flag'; src/aiop_tool.o:(.bss+0x0): first defined here
+| ...ld: src/aiop_logger.o:(.bss+0x2): multiple definition of `_verbose_flag'; src/aiop_tool.o:(.bss+0x2): first defined here
+
+Reference: https://gcc.gnu.org/gcc-10/porting_to.html
+As a workaround, legacy C code where all tentative definitions should be
+placed into a common block can be compiled with -fcommon.
