It looks like the gcc environment on Android is different than on
regular Linux.

gcc comes with a small run-time environment that is linked to all
binaries, even dietlibc ones.  This run-time is called libgcc, and these
error message indicate that it references symbols that are not found in
dietlibc.

Some of the symbols are definitely exported by dietlibc, so something
fundamental is wrong here.  My guess is that "androideabi" is not
compatible with the ABI that dietlibc implements on ARM.

I have no idea how to fix this.  It may be necessary to do a separate
port of dietlibc to support this ABI.

I wonder if regular arm-linux dietlibc programs run on Android.
They ought to, if Google did not meddle with the syscall ABI.
