Subject: [PATCH] share/text.h: fix build failure against gcc-10
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On gcc-10 (and gcc-9 -fno-common) build fails as:

```
cc .. -o neverball ...
ld: ball/st_save.o:(.bss+0x0):
  multiple definition of `text_input'; share/text.o:(.bss+0x0): first defined here
```

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.
