scons: Capture TMPDIR envvar
During gem5 build, the compiler may produce some large intermediate
files. The default path is /tmp, but in some usecase, it's under a small
file system, and we may want to change the storage path to a sufficient
large file system. This CL captures TMPDIR environment variables, to
allow users change the default temporary directory.
