[Buildroot] [git commit] libffi: add patch to fix library installation location

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=80e47a533bed9745f56379e45e4ec136a1590697
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The libffi library was installed in a wrong directory when using the
non-default variant of a multilib toolchain. We fix this by patching
the libffi Makefile.am to install its library in a normal
location. The patch has been submitted upstream.

Fixes:

+Subject: [PATCH] Fix installation location of libffi
+
+The libffi is currently declared as toolexeclib_LTLIBRARIES. In many
+cases, toolexeclib libraries will be installed in /usr/lib, so it
+doesn't make any difference.
+
+However, with multilib toolchains, they get installed in a
+subdirectory of /usr/lib/. For example, with a Sourcery CodeBench
+PowerPC toolchain, if the e500mc multilib variant is used, the libffi
+library gets installed in /usr/lib/te500mc/. This is due to the
+following code in the configure script:
+
+  multi_os_directory=`$CC -print-multi-os-directory`
+  case $multi_os_directory in
+    .) ;; # Avoid trailing /.
+    *) toolexeclibdir=$toolexeclibdir/$multi_os_directory ;;
+  esac
+
+Once the library is installed in /usr/lib/te500mc/, nothing works
+because this installation location is inconsistent with the
+installation location declared in libffi.pc.
+
+So, instead of using this bizarre toolexeclib_LTLIBRARIES, simply use
+the more standard lib_LTLIBRARIES, which ensures that the libffi
+library is always installed in /usr/lib.
