Backport #7904: test_spawn_too_long_path(TestProcess) fails on PPC64

=begin
I observe following error on PPC64:
7) Failure:
test_spawn_too_long_path(TestProcess) [/builddir/build/BUILD/ruby-2.0.0-r39357/test/ruby/test_process.rb:1383]:
[Errno::ENOENT, Errno::E2BIG, nil] expected but nothing was raised.
8) Failure:
test_aspawn_too_long_path(TestProcess) [/builddir/build/BUILD/ruby-2.0.0-r39357/test/ruby/test_process.rb:1388]:
[Errno::ENOENT, Errno::E2BIG, nil] expected but nothing was raised.

I am quite sure, that there was no such test error testing with rev38848. Not sure if that might be related to 38934.

Nobu, could you check it if it is critical or not for 2.0.0p0?

It seems a miss in the test probably.
Could you try with r39375?

Testing with r39383

   [ruby-core:34833].

But one of the test errors (test_spawn_too_long_path) is gone.

Failure of the same two tests were observed also on Solaris10 before r39374.
After r39375, failure of test_spawn_too_long_path also vanished on Solaris10.

On Solaris10, with r39376,

TestProcess#test_aspawn_too_long_path = sh: a: not found
sh: a: not found
sh: a: not found
sh: a: not found
(snip many lines)
sh: a: not found
sh: a: not found
sh: a: not found
sh: fork failed - too many processes

and

13. Failure:

    [ruby-core:34833].
    [Errno::ENOENT, Errno::E2BIG] expected but nothing was raised.
