Fix false FAIL on gdb.base/stap-probe.exp, due to ICF optimization
GCC 6's ICF optimization pass is making the declaration of 'm1' and
'm2', on gdb.base/stap-probe.c, to be unified. However, this leads to
only one instance of the probe 'two' being created, which causes a
failure on the testsuite (which expects a multi-location breakpoint to
be inserted on the probe).
This patch fixes this failure by declaring a dummy variable on 'm1',
and using it as an argument to m1's version of probe 'two'. Since we
do not care about the contents of the functions nor about the
arguments of each probe 'two', this is OK.
gdb/testsuite/ChangeLog:
2016-09-11 Sergio Durigan Junior <sergiodj@redhat.com>
Jan Kratochvil <jan.kratochvil@redhat.com>
* gdb.base/stap-probe.c (m1): New variable 'dummy', necessary to
make m1's definition to be different from m2's. Use 'dummy' as an
argument for probe 'two'.

End of assembler dump.
The .exp patch is an obvious typo fix I think. The regex was written to
accept "ADDR in main" and I find it OK as checking .debug_line validity is not
the purpose of this testfile.
gcc-4.8.5-11.el7.x86_64 did not put the 'mov $0x0,%eax' instruction there at
all so there was no problem with .debug_line.

Fix missing files for ld when test suite not compiled in the source directory
This patch fixes an issues with six test suite expect files that do not
run correctly when the test suite is not built in the source directory. The
issue is these tests are not using the current "standard_testfile" call
but rather using the older set command to initialize the "testfile",
"srcfile" and "binprefix" variables or are missing the set for the
"binprefix" variable.

Replace sprintf with xsnprintf in nat/linux-osdata.c
I see the following build warning when I build GDB with GCC trunk.

cc1plus: all warnings being treated as errors
The warning is a false positive, but we can workaround it by replacing
sprintf with xsnprintf. On the other hand, it is always preferred to
use xsnprintf.
