Subject: [PATCH] Support gcc10 compilation
gcc10 now defaults to -fno-common, and with gcc10 menu-cache compilation fails like
/bin/ld: menu-merge.o:menu-cache-gen/menu-tags.h:167: multiple definition of `DirDirs'; main.o:menu-cache-gen/menu-tags.h:167: first defined here
/bin/ld: menu-merge.o:menu-cache-gen/menu-tags.h:164: multiple definition of `AppDirs'; main.o:menu-cache-gen/menu-tags.h:164: first defined here
/bin/ld: menu-merge.o:menu-cache-gen/menu-tags.h:52: multiple definition of `menuTag_Layout'; main.o:menu-cache-gen/menu-tags.h:52: first defined here
....
This patch fixes compilation with gcc10: properly declaring variables in header with "extern", and also removing some unneeded variables in header files.
