[PATCH] libstdc++: Fix python/ not making install directories

[Arsen Arsenović via Gcc-patches]

I'm unsure why this issue only started manifesting now with how old this
code is, but this should fix it.

libstdc++-v3/ChangeLog:

        * python/Makefile.am: Call mkinstalldirs before INSTALL_DATA
        when installing gdb scripts.
        * python/Makefile.in: Regenerate.

Hi,

Someone spotted on IRC spotted an error: if trying to install to a fresh
prefix/sysroot with --enable-libstdcxx-debug, the install fails since it's
intended target directories don't exist.  I could replicate this on
r13-3944-g43435c7eb0ff60 using

$ ../gcc/configure --disable-bootstrap \
        --enable-libstdcxx-debug \
        --enable-languages=c,c++ \
        --prefix=$(pwd)/pfx

Install tested on x86_64-pc-linux-gnu with and without
--enable-libstdcxx-debug.
