This path fix build failed when gem5's path contains Non-ASCII characters. build_tools/marshal.py embed "abspath" and "modpath" into the generated c++ file. However, if either of them contains Non-ASCII characters, marshal.py will throw an exception. This can be fixed if we set a suitable $LANG for gem5py. For example, we can simply set $LANG=en_US.UTF-8 in src/SConscript to fix this. This patch fixes this bug by passing the host's $LANG environment variable to gem5py. Because for users who may use Non-ASCII characters, their $LANG is generally set to their native language (e.g. zh_CN.UTF-8, en_US.UTF-8, etc.), which contains Non-ASCII characters. Also, it is more reasonable to use the host $LANG than to directly hard-code the $LANG used by gem5py into a language that supports non-ASCII characters.
