            Bug ID: 13226
           Summary: external toolchain helper deletes libs if link doesn't
                    exist
           Product: buildroot
           Version: 2020.08
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org
          Reporter: protectivedad at gmail.com
                CC: buildroot at uclibc.org
  Target Milestone: ---

The function copy_toolchain_lib_root in helpers.mk never checks to see if
LIBPATH actually exists. If it doesn't say due to the readlink -f it processes
a blank LIBPATH which deletes items in the library that have been already
copied.

A change to the while true to test for LIBPATH != "" will fix this.
