gcc-target 5.1: fix for libcc1
Fixed: * gcc 5 introduces a plugin libcc1.so, which is used by gdb, the target gcc didn't build it in the past because gcc_cv_objdump is null, and the error was: gcc-5.2.0/libcc1/configure: line 14531: -T: command not found This only happens for tar gcc as the code shows: if test x$build = x$host; then export_sym_check="objdump${exeext} -T" elif test x$host = x$target; then export_sym_check="$gcc_cv_objdump -T" else export_sym_check= fi * Install libcc1.so and libcc1plugin.so to $(libexecdir)/gcc/$(target_noncanonical)/$(gcc_version) as lto-plugin did. * Use sed command to fix bad RPATH iussue.

+Subject: [PATCH] libcc1: fix libcc1's install path and rpath
+
+* Install libcc1.so and libcc1plugin.so into
+ $(libexecdir)/gcc/$(target_noncanonical)/$(gcc_version), as what we
+ had done to lto-plugin.
+* Fix bad RPATH iussue:
+ gcc-5.2.0: package gcc-plugins contains bad RPATH /patht/to/tmp/sysroots/qemux86-64/usr/lib64/../lib64 in file
+ /path/to/gcc/5.2.0-r0/packages-split/gcc-plugins/usr/lib64/gcc/x86_64-poky-linux/5.2.0/plugin/libcc1plugin.so.0.0.0
+ [rpaths]
+
+Upstream-Status: Inappropriate [OE configuration]
