Description of problem:
busybox command 'wc' fails on s390x when redirecting stdin:
# echo "asdf" | busybox wc -l
wc: : No such file or directory

The code from wc_main (wc.c) does:
    *--argv = (char *) bb_msg_standard_input;

which after disassembly (objdump or gdb) gives:
0000000080099f58 <wc_main>:
...
    80099fd4:   e3 a0 af f8 ff 71       lay     %r10,-8(%r10)
    80099fda:   c0 20 00 02 35 87       larl    %r2,800e0ae8 <bb_msg_invalid_arg+0x1d>

The address of "bb_msg_standard_input" is not even:
800e0ae9: <bb_msg_standard_input>

The problems appears to be in alignment of "bb_msg_standard_input". 
# define ALIGN1 __attribute__((aligned(1)))
const char bb_msg_standard_input[] ALIGN1 = "standard input";

larl instruction can generate only even addresses. The address, which is used (800e0ae8) is the end of bb_msg_invalid_arg, which is "\0".

Version-Release number of selected component (if applicable):
RHEL6.3-20120507.n.1
busybox-1.15.1-15.el6.s390x

How reproducible:
100%

Steps to Reproduce:
1. echo "asdf" > test
2a. busybox wc -l < test
or
2b. echo "asdf" | busybox wc -l
  
Actual results:
wc: : No such file or directory

Expected results:
1

From z/Architecture Principles of Operation SA22-7832-07:
"Only even addresses (halfword addresses) can
be generated. If an odd address is desired,
LOAD ADDRESS can be used to add one to an
address formed by LOAD ADDRESS RELATIVE
LONG."
