[bug#59992] [PATCH 1/2] tests: Fix 'type defaults' error in link_cond due to main not being properly declared

From: Frédéric Bérat <[email protected]>

This is related to an effort to prepare Automake for future GCC/Clang
versions which set c99 as default standard to be used.
Not properly declaring main as "int main(...)" is rejected since c99.
