I think i have managed to solve the problem and produce
almost valid elf files on FreeBSD. The two patches attached
address a few problems (trying to explain to the
best of my knowledge; i am not very familiar with ELF and
the FreeBSD ELF conventions):

1. ELF file format
  tcc produces an ELF executable which is good for linux but
  not for FreeBSD. It misses the PHDR section which is almost
  mandatory for shared executables, puts in the .dynsym section
  some relocation info that FreeBSD expects to be in .got,
  and expect the relocation sections to be contiguous.

  patch-tccelf.c tries to address the above problem using
  conditional sections (so hopefully can be imported upstream)
  and also adds the ability to override the name of the dynamic
  loader through an environment variable (this is important to
  debug tcc).

2. predefined macros

  patch-libtcc.c adds/fixes some predefined macros when compiling
  on FreeBSD: these are __FreeBSD__ and the usual set of
  __i386__ and __unix__ variants.
  It also sets __INTEL_COMPILER so we can grab the __aligned
  macro from cdefs.h , otherwise many programs would fail

The resulting elf file is still not 100% correct -- if you strip it,
the program will not run (presumably there is some dangling reference).
Other than that, program do seem to run correctly.

It would be nice to integrate these patches in the main repository.
The FreeBSD specific code is in #ifdef so it should not harm
linux users
	cheers

0a3bcb57f6 fix 32bit asm
The new 16bit code was causing wrong 0x66 prefixes
in 32bit code.

The fix possibly breaks the feature on 16bit asm.
