gcc installs a libstdcxx-...so-gdb.py file that gdb will load automatically when it loads libstdcxx.so, via the mechanism described at [1]. However, the auto-load file installed by gcc contains hardcoded paths referring to the location where the (external) toolchain was built, which are normally not available. Fix up the paths in the load file so that the pretty printers can be loaded automatically. Note that gdb will only auto-load the file if its location is marked as 'safe'. A subsequent commit will take care of that. Technically, there could be more than one load file, e.g. in lib and usr/lib, so fix them all. This was for example observed in BR2_TOOLCHAIN_EXTERNAL_ARM_AARCH64. In a very specific case with a local custom toolchain, there were actually two 'python' directories, which would break the sed command, so arbitrarily limit to the first one encountered.
