Disable `-pedantic` for NaCl's GCC 4.4(.3).

It complains too much about comma at the end of enumeration list in
dependent projects even as that is perfectly valid code. My own 4.4.7
doesn't do that.

Cherry-picked from compatibility branch, as Corrade's master is
often used along with compatibility NaCl binaries.
Utility: send messages through NaClConsoleStreamBuffer line by line.

Chromium has line length limits which truncate the messages.
Utility: add TODO to NaClConsoleStreamBuffer line-by-line.

It's probably NaCl issue, as calling `console.log()` directly in
Chromium doesn't truncate anything.
