Fails to link under gcc 10

[tyrylu]

Hello.
When checking the logs after a Fedora mass rebuild using gcc 10, i came acros a link failure in speech_tools. You needed to add -fnocommon to the gcc args to fix it.
The error was:

Link Shared Library estools
if [ -n "" ] ; then libs='     -lncurses -lasound  -ldl  -lm  -lstdc++
-fopenmp ' ; fi ;\
gcc -shared -o libestools.so.2.5.0.1 shared_space/*.o  $libs

Please try again vs. ToT master

i came here from https://aur.archlinux.org/packages/festival-patched-hts because the build fails, and after applying a patch as in #21, it succeeded..

UPDATE: actually after that patch, it failed further at:
