   Currently libffi head can be built on x86_64-apple-darwin14 with
Xcode 6.1 using just...

mkdir build
cd build
../configure

and 'make check' shows...

Unfortunately, the -m32 build for both compilers are broken. On system

Any ideas on how to fix this issue with sysv,S?

For some reason, the configure test

        echo '.text; foo: nop; .data; .long foo-.; .text' > conftest.s
...
        AC_DEFINE(HAVE_AS_X86_PCREL, 1,
                  [Define if your assembler supports PC relative relocs.])


fails on darwin.  Which leads to

#ifdef HAVE_AS_X86_PCREL
# define PCREL(X)       X - .
#else
# define PCREL(X)       X@rel
#endif

which leads to the error.  Curiously, "X-." does seem to work on Darwin,
and you ought to be able to get sysv.S to compile if you edit that ifdef.

If you could figure out why the assembly works, but the configure test
doesn't, that'd be great.
