           Summary: Buildroot fails to copy libstdc++ to target when using
                    external toolchain
           Product: buildroot
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org

When buildroot builds arm-linux-uclibcgnueabi toolchain, some libraries get
installed into <sysroot>/lib, others - including libstdc++ - into
<sysroot>/usr/arm-linux-uclibcgnueabi/lib. 
If I use such a toolchain as an external toolchain for another buildroot build,
buildroot does not find libraries in <sysroot>/usr/arm-linux-uclibcgnueabi/lib.
Previous versions of buildroot used -print-file-name option of gcc to locate a
library. Current version only checks in <sysroot>/lib folder.
