If we are OK relying on rudimentary perl[1], then:

  perl -le "print((stat)[7]) for @ARGV"

works. If you want it more readable, then maybe:

  perl -MFile::stat -le "print stat(\$_)->size for @ARGV"

Both of those should work with even antique perl versions.

[1] I'd also be fine with implementing a test-tool helper in C that
    behaves like stat(1). Or we could punt on that until somebody feels
    like trying to eradicate perl (because this is far from the first
    perl one-liner in the test suite).
