[ci]: try building all combination with tcc (#338)

this will hopefully catch issues like [337] in the future.

not using gcc and/or clang since we have 5 build options right now,
which means 2^5 = 32 different combination. using gcc/clang would take
too much resources and time; meanwhile tcc is lightning fast.
