That's because I took care to add the right flags everywhere they were
needed, I just messed this one up due to autotools differences.

Before things built because we shoved absolutely everything in FLAGS so it
was present in every compile operation. It's pretty harmless for CFLAGS, but
for libs it can have undesired consequences.

Examples: dch said on irc that his icu erroneously links ssl on windows and
it used to be that with --with-js-lib we'd link our icu driver against
spidermonkey.

Especially as we pull in more deps like yajl, snappy, etc, I prefer that it
be this way, where we're careful and explicit about what we pass where. In
my mind these commits just uncovered a subtle bug in our build system. The
build broke because we finally saw what we were forgetting to specify.
