With r8c, doing an ndk-build without having changed any sources seems to often cause a complete rebuild.  We didn't have this problem with r8b.  Is anyone else experiencing this?  I'm wondering if it's somethiing peculiar to our build setup.

Yes, you are not the only one. I'm having same issue. (not in r8b)

I believe that the fix is easy: use order-only prerequisite, (cf. http://www.gnu.org/software/make/manual/html_node/Prerequisite-Types.html).

The patch is to change a single line 289 in build/core/definitions.mk from 

$1: $$(__ndk_file_dir)

to 

$1: | $$(__ndk_file_dir)

Enjoy,
Alex Cohn

Great!  Works perfectly, thanks.

WTF, how something like that could have ever been released?
Can anybody at google confirm that they actually use their own tools and test them occasionally??

Alex, maybe you could communicate that fix to google devs? They still didn't fix that bug in their ndk download. Millions of developers will have that issue because google devs simply decided not to test it. Everytime I need to setup android build machine I google "alex r8c rebuild patch" :) Works well.
Can you give more info what was the problem and how that pipe fixes it? Seems that previous NDKs didn't have similar code in them, it probably took some time to figure out that fix?
