Are you only building newlib just to make testing faster?

[jvoung (off chromium), 2014/05/21 21:10:56]

No it's not just the testing time. There are some assumptions in the test that
are specific to newlib right now:

- the number of validation queries/settings varies.  It would be more with glibc
-- from the open_resource uses, and fewer for PNaCl because the main nexe is
placed in a temp file.
- the tester jig is hardcoded to inherit from the newlib class
- the test directory path commandline flag for loading the unpacked extension is
specific to newlib right now too

It might be good to at least add the glibc case but I just didn't do that yet.

Added a comment if that helps.
