The above could benefit from some extra commenting to explain the choice
of linker options (--enable-new-dtags ?) or C preprocessor variables
(-D_REENTRANT). I'd have to dig a bit deeper than I'd like to have an
understanding of these.

The rest LGTM! Feel free to push a revised version in which you explain
a little bit the choice of linker/preprocessor options.
Thank you!
