tests: generate test.ref with TCC instead of host CC

Browse Source 
The promote char/short funcret test in tcctest.c invokes
undefined behavior (narrow return without extension). GCC
produces one set of values, TCC with PROMOTE_RET produces
correct ABI-compliant values. Generate the reference with
TCC so self-tests are consistent.
