I'm having a persistent issue building the filesystem as per the instructions on the AM335x Android 4.1.2/Devkit 4.0.1 Developer's Guide wiki (http://processors.wiki.ti.com/index.php/TI-Android-JB-4.1.2-DevKit-4.0.1_DeveloperGuide).
The u-boot and kernel builds seem to go fine, but when I try the file system build with the following command
~/rowboat-android/kernel$ make TARGET_PRODUCT=am335xevm_sk OMAPES=4.x -j4
I get the following output in the middle dealing with building pmem.o

I get this whether I use the git version or the tarball-download version of the source. Also happens whether I build for "am335xevm" or "am335xevm_sk" options.
I've tried changing some of the default config options but to no effect so far. I'm copying the .config file anyway. 5466.config.txt
I would appreciate any help understanding and resolving the issue here.
