scons: fix build failed caused by Non-ASCII directory path
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.
