If you want to make a deb file, why not have a Debian source package and make 
it build depend on libtcc-dev as well? If that is too much hassle, you should 
at least link against the libtcc.a file provided by libtcc-dev (see below).

Doing the above should fix the issue as the libtcc.a in libtcc-dev will expect 
libtcc1.a in the same path as the path for libtcc1.a in the tcc package.

I'd rather say it's incorrectly hardwired in the libtcc you built. 
Alternatively the deb you provide could include the libtcc1.a in the path it 
expects it to be but the solution above is much better.
