After some tests, I found two methods to "remove" that Python error:
1. After the command "make -f client.mk" is fail, just execute it again. I.e.
make -f client.mk
make -f client.mk
2. Modify configure.py to set the current default string encoding from "ascii"
to "utf-8" :
sed -i '/import sys/ a\
\
reload(sys) \
sys.setdefaultencoding("utf-8")' configure.py
make -f client.mk
The reference of the function "sys.setdefaultencoding()" :
https://docs.python.org/2.7/library/sys.html#sys.setdefaultencoding
However, I found that the use of "sys.setdefaultencoding()" has always been
discouraged. (Reference:
http://stackoverflow.com/questions/3828723/why-should-we-not-use-sys-setdefaultencodingutf-8-in-a-py-script
)
Anyhow, if we modify the default string encoding, the output of the building
process becomes:
mkdir -p '/sources/firefox-48.0.2/firefox-build-dir/'

Clobber not needed.

Reexecuting in the virtualenv
As you see, GCC 6.x will use something likes "^~~~" to indicate the errors and
the current building script cannot handle it.
