--- Comment #8 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
> Confirmed that the proposed patch eliminates both the bootstrap failure

> -m64.
When running
make -k -j8 check RUNTESTFLAGS="--target_board=unix'{-m32,-m64}'"
I get
=== libffi tests ===
Running target unix-m64
ERROR: couldn't load description file for unix-m64
and if I run the test in x86_64-apple-darwin14.0.0/libffi/testsuite/ with
make -k check RUNTESTFLAGS="--target_board=unix'{-m32,-m64}'"
I get
