"make check" fails on Arch Linux

On Arch Linux, make check fails with following messages.

$ make check                                                              (git)-[bigint]

Following command fixes the error.

sed -i 's/ python / python2 /' mk/tests.mk

Thanks to @brson, but another error occured.

  File "/home/nksm/dev/rust-repo/src/etc/check-summary.py", line 17
    return sum(map(lambda (f, s): len(s.get(t, [])), summaries))
                          ^
SyntaxError: invalid syntax

I confirmed following command fixes the error, and no errors occures.

find src/etc -name "*.py" -exec sed -i 's/env python$/env python2/'

That should be fixed too now.
