On gcc-10 (and gcc-9 -fno-common) sasquatch build fails as:
c++ ./LZMA/lzmalt/*.o unsquashfs.o ... -o sasquatch
ld: unsquash-1.o:squashfs-tools/error.h:34:
multiple definition of `verbose'; unsquashfs.o:squashfs-tools/error.h:34: first defined here
gcc-10 will changed the default from -fcommon to fno-common:
https://gcc.gnu.org/PR85678.
The change splits declaration and definition.

Without the change build on clang-12 or upstream gcc-12 fails as:
$ nix build --impure --expr 'with import ./. {}; sasquatch.override { stdenv = clang12Stdenv; }' -L
...
c++ ./LZMA/lzmalt/*.o ... -o sasquatch
ld: squashfs-tools/./error.h:34: multiple definition of `verbose'; unsquashfs.o:error.h:34: first defined here
Until upstrea fixes it by fixing `verbose` variable declaration at:
devttys0/sasquatch#44
and fork rebases let's set `-fcommon` explicitly.
