libffi: Update to 3.0.13
New patch is required to fix the location of the libdir defined i the libffi.la file which caused a bad RPATH (/usr/lib/../lib) due to the gcc -print-multi-os-directory returning ../lib. Remove Aarch64 patches as it is now supported upsteam. Other patch code is also upstreamed (From OE-Core rev: 6f1caa75b181eb40fdbbd4d9979a5f61c0b9435a) Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

26+# SYNOPSIS
27+#
28+# AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
29+#
30+# DESCRIPTION
31+#
32+# FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
33+# added in between.
34+#
35+# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
36+# CFLAGS) is used. FLAGS-VARIABLE is not changed if it already contains
37+# FLAG. If FLAGS-VARIABLE is unset in the shell, it is set to exactly
38+# FLAG.
39+#
40+# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

101+# SYNOPSIS
102+#
103+# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
104+#
105+# DESCRIPTION
106+#
107+# Check whether the given FLAG works with the current language's compiler
108+# or gives an error. (Warnings, however, are ignored)
109+#
110+# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
111+# success/failure.
112+#
113+# If EXTRA-FLAGS is defined, it is added to the current language's default
114+# flags (e.g. CFLAGS) when the check is done. The check is thus made with
115+# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
116+# force the compiler to issue an error when a bad flag is given.
117+#
118+# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
119+# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.
