+libffi's configure assumes that cross-compiled builds are complicated and
+introduces convoluted path manipulation involving gcc search paths to the
+install paths, resulting in paths like -L/usr/lib/../lib/ appearing in
+libffi.pc.  When pkg-config is then used to obtain the linker flags for libffi
+it can't tell that this path is on the default search path and returns
+$SYSROOT/usr/lib/../lib which then gets written all over the target sysroot.
+This then means the sstate can't be shared and triggers QA errors.
+
+As this block is generally pointless, disable it.

+SUMMARY = "A portable foreign function interface library"
+HOMEPAGE = "http://sourceware.org/libffi/"
+DESCRIPTION = "The `libffi' library provides a portable, high level programming interface to various calling \
+conventions.  This allows a programmer to call any function specified by a call interface description at run \
+time. FFI stands for Foreign Function Interface.  A foreign function interface is the popular name for the \
+interface that allows code written in one language to call code written in another language.  The `libffi' \
+library really only provides the lowest, machine dependent layer of a fully featured foreign function interface.  \
+A layer must exist above `libffi' that handles type conversions for values passed between the two languages."
