+Subject: [PATCH] tftp-hpa: fix build failure against gcc-10
+
+On gcc-10 (and gcc-9 -fno-common) build fails as:
+
+```
+x86_64-pc-linux-gnu-gcc -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu tftp.o main.o ../common/libcommon.a -lreadline -liberty -o tftp
+ld: main.o:(.bss+0x40):
+ multiple definition of `toplevel'; tftp.o:(.bss+0x100): first defined here
+collect2: error: ld returned 1 exit status
+make[1]: *** [Makefile:12: tftp] Error 1
+```
+
+gcc-10 will change the default from -fcommon to fno-common:
+https://gcc.gnu.org/PR85678.
+
+The error also happens if CFLAGS=-fno-common passed explicitly.
