This whole issue is due to buggy CMake.

When installing binaries into buildroot, CMake removes RPATH from the
binaries.  The RPATH removal appears to be a low-level stuff hardcoded
in C+plus.  Sometimes it works.

+       * Source/cmComputeLinkInformation.cxx: BUG: Do not mangle symbols
+         when editing RPATHs
+
+         In ELF binaries the .dynstr string table is used both for the
+         RPATH string and for program symbols.  If a symbol name happens
+         to match the end of the build-tree RPATH string the linker is
+         allowed to merge the symbols.
+
+         We must not allow this when the RPATH string will be replaced
+         during installation because it will mangle the symbol.  Therefore
+         we always pad the end of the build-tree RPATH with ':' if it will
+         be replaced.  Tools tend not to use ':' at the end of symbol
+         names, so it is unlikely to conflict.  See issue #9130.
