Bug description:
Attempting build even a simple hello world kernel on ppc64el fails
with the following error:
/usr/bin/ld.bfd.real: cannot find arch/powerpc/lib/crtsavres.o: No
such file or directory
To reproduce, the Hello World kernel module from
http://tldp.org/LDP/lkmpg/2.6/html/x121.html#AEN128 , using it and the
Makefile at http://tldp.org/LDP/lkmpg/2.6/html/x181.html#AEN189 ,
gives the following result:
$ make
make -C /lib/modules/3.13.0-24-generic/build M=/home/sbeattie/tmp/hello
modules
make[1]: Entering directory `/usr/src/linux-headers-3.13.0-24-generic'
CC [M] /home/sbeattie/tmp/hello/hello-1.o
Building modules, stage 2.
MODPOST 1 modules
CC /home/sbeattie/tmp/hello/hello-1.mod.o
LD [M] /home/sbeattie/tmp/hello/hello-1.ko
/usr/bin/ld.bfd.real: cannot find arch/powerpc/lib/crtsavres.o: No such

make[2]: *** [/home/sbeattie/tmp/hello/hello-1.ko] Error 1
make[1]: *** [modules] Error 2

A similar build failure is reproduced with the test-kernel-
security.py:test_072_strict_devmem() test failure from the lp:qa-
regression-testing tree.
Seen with 3.13.0-24.46 and 3.13.0-24.47.
