To do this, I ran the following command:

make O=mybuild E=hello uimage BOOTSTRAP_NO_STRIP=1

I had been looking in the general build configuration, but the "Strip binaries 
on install" (BID_STRIP_PROGS) option evidently only applies to bundled 
programs, not the bootstrap payload itself.

The above binaries have now been replaced with ones that include symbol 
information. Previously, I had been looking at the dump for boot_modules.o and 
didn't notice anything particularly unusual, but I must admit that I don't 
know the more exotic ARM instructions.

Thanks once again for taking a look!
