Well, to me the better patches are those that make the code smaller
rather than bigger ;)

As I understand it is possible to support multilib without any special
code in tcc.  Without CONFIG_TCC_MULTILIB_SUBDIR, AFF_MULTILIB,
CONFIG_TCC_EXTRA_LDDIR, CONFIG_TCC_INCSUBDIR, just without anything
"MULTI_EXTRA_SUB" whatsoever.

Do you think that is possible?

Likely lack:
$ git checkout release_0_9_25 tccelf.c

    /* name of ELF interpreter */
    #if defined __FreeBSD__
    static char elf_interp[] = "/usr/libexec/ld-elf.so.1";
    #elif defined TCC_ARM_EABI
    static char elf_interp[] = "/lib/ld-linux.so.3";
    #elif defined(TCC_TARGET_X86_64)
    static char elf_interp[] = "/lib/ld-linux-x86-64.so.2";
    #elif defined(TCC_UCLIBC)
    static char elf_interp[] = "/lib/ld-uClibc.so.0";
    #else
    static char elf_interp[] = "/lib/ld-linux.so.2";
    #endif
