m_kato: thank you for the patch.

Ted: who's the best person to review build system patches
for Android?  You, Brad Lassey, or Mike Hommey?

m_kato: why doesn't Android-arm need this change?

There is no libpthread.so in NDK.  On arm toolchain, -lpthread doesn't cause error even if there is no libpthread.so.  But, on x86 toolchain, it causes error due to missing library.

So we should remove -lpthread if target is Android.

r=wtc.

Ted, when you review this patch, please verify
that the Android NDK does not have libpthread.so.

I checked, the NDK does not include a pthread library, just the headers. I'm not sure why this didn't break on the ARM build.

This patch looks fine.

The change you linked to isn't the same as the patch posted here...and that patch doesn't appear in current m-c.

You're right.  Sorry, the confusion was on my part.  Ted, was this excluded from the NSPR tag you created?  If yes, I think we need to create another one...

I tagged that beta during the week of September 12th, and I landed this the 22nd, so yeah, this wouldn't have made the tag.
