Fix libffi issues with dynamic linking (now with mac support)

2020-08-06T16:02:55+00:00

HAVE_HIDDEN_VISIBILITY_ATTRIBUTE was unset, leading to symbols not being
properly marked as hidden in assembly. This causes issues for PIC code
generation, which is needed when supporting the shared library version
of libffi on x86. This patch also fixes some missing support for Mac,
since they use `.private_extern` instead of `.hidden` in assembly files.
