Bug #12500: TestProcess#test_aspawn_too_long_path fails on mips with "argument too big"

https://bugs.ruby-lang.org/issues/12500#change-104244



* Author: zeha (Christian Hofstaedtler)

* Status: Open

* Priority: Normal

* ruby -v: ruby 2.3.1p112 (2016-04-26) [mips-linux-gnu]

* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: REQUIRED

----------------------------------------

Recently in Debian we've enabled `make check` and this is one of the test failures we get for ruby2.3, on mips:



```

I think is caused by some array or string mangling code used by Process.spawn, but can't be sure.



Please also backport any fixes for this to 2.3.
