The cause seems to be that the generated executable name is fixed
to "a.exe" instead of depending on the test name:

113_btdll.test: T1 = \
    $(TCC) -bt $1 -shared -D DLL=1 -o a1$(DLLSUF) && \
    $(TCC) -bt $1 -shared -D DLL=2 -o a2$(DLLSUF) && \
    $(TCC) -bt $1 a1$(DLLSUF) a2$(DLLSUF) -Wl,-rpath=. -o a.exe && \
    ./a.exe

T2 = $(if $(NORUN),$1 -o a.exe && ./a.exe,-run $1)

GEN-CC = $(CC) -w -std=gnu99 $(FLAGS) $1 -o a.exe && ./a.exe $(ARGS)
