Comment (by kencu):

 On i386 Tiger, we see warnings at the same file, but not errors:
 {{{
 355     ../src/x86/sysv.S:808:section type does not match previous section
 type
 356     ../src/x86/sysv.S:814:section type does not match previous section
 type
 }}}

 I did manage to get past that spot with a small edit to the sysv.S source
 file:
 {{{
 - .section __TEXT,__text,coalesced,pure_instructions;
 + .section __TEXT,__textcoal_nt,coalesced,pure_instructions;
 }}}

 but then still ran into the same linker error in the end:
 {{{
 ld: in src/x86/.libs/sysv.o, in section __TEXT,__eh_frame reloc 0: bad
 length for GENERIC_RELOC_SECTDIFF
 }}}

 working on it...

 It is well known, as you point out, that the libffi assembler is advanced
 in nature, and no doubt the 32bit darwin part of it suffers more than
 most. We are trying to see if we can tweak it to build with the system
 toolchain, as otherwise our bootstrapping is complicated.

 We could consider salting away libffi 3.2.1 in a directory and building
 some llvm version against it (3.7?) that gets us to a current libffi
 version. But I'm hoping we don't have to do that as it just adds ever more
 complexity to supporting and bootstrapping these older systems that I
 would live to avoid.
