[ptxdist] [PATCH 1/2] libffi: Adjust build options.

[Christian Melki <christian.melki@t2data.com>]

When upgrading automake, libffi failed to build due to
a makefile error. The error is triggered when using options
we don't really need. Circumvent the issue by changing options
and also improve a few others.

* Rearrange one option.

* Disable internal builddir in the srcdir and disable using gcc
as discovery for multidir arch directories.

* Force static trampolines. Dynamic ones are a security issue.
Now this might break some programs and probably make debugging
using gobject introspection difficult, but otoh, it stops usage
of self modifying code.

* Keep patches. I guess they can both go away, but I don't
see much harm in continuing to use them.
