Subject: [PATCH] disabled packages: add tcc from unstable repo

TCC is a Tiny C Compiler. It doesn't support PIE executables but has
been added for its ability to act as C code interpreter. I don't know
whether package is still needed at all and considering its limited
usage scope on Android, I have moved it to disabled packages.
