Let me summarize where we are on FreeBSD i386 and x86_64 with mod:
x86_64:
$ uname -m
amd64
$ gcc --print-file-name=crt1.o
/usr/lib/crt1.o
$ find /usr -name crt1.o
/usr/lib32/crt1.o
/usr/lib/crt1.o
$ ./configure
Binary directory /usr/local/bin
TinyCC directory

Hmm and now I see that this hunk also generally breaks building the target
compilers like x86_64-tcc, because they don't get NATIVE_DEFINES from
config.mak, and hence no -DCONFIG_LDDIR even if configure would have found
the correct one, so it now defaults to /lib, and boom.

Can we just take a moment to appreciate how a pull request with automated
testing (a la Travis CI) would have made this error obvious *before* it was
added to mob?

Yes, I've implemented the GCC way privately already (necessary for e.g.
linux kernel).

no more core dump but still unable to link with std C.

According to Christian, we have at least one major compiler (VC++) whose
behavior matches tcc's current behavior and another (GCC) whose behavior
differs. While it would be nice to just pick one implementation and go with
it, I am personally much more concerned with binary compatibility with
one's

It depends on the ABI. The ARM EABI defines those details in
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042f/IHI0042F_aapcs.pdf
section 7.1.7. But I don't know if we adhere to those rules when
