The MinGW build for Windows has special cases where exported function contain additional prefix: __emutls_v.per_lcore__* To avoid adding those prefixed functions to the version.map file the map_to_def.py script was modified to create a map file for MinGW with the needed changed. The file name was changed to map_to_win.py and lib/meson.build map output was unified with drivers/meson.build output Signed-off-by: Tal Shnaiderman <talshn@mellanox.com>
