i386: use __fixdfdi instead of __tcc_cvt_ftol
Variants __fixsfdi/__fixxfdi are not needed for now because the value is converted to double always. Also: - remove __tcc_fpinit for unix as it seems redundant by the __setfpucw call in the startup code - avoid reference to s->runtime_main in cross compilers - configure: fix --with-libgcc help - tcctok.h: cleanup
