remove remnants of old Mach-O workaround

I happened to run readelf on an ELF file created by Guile.  readelf
complained about invalid values for DW_FORM_strp.  At first I assumed
this was just a Guile bug, but eu-readelf did the right thing, so I
looked a bit deeper.

I came across some old Mach-O code to bias some offsets by section
addresses.  Guile, unlike many ELF writers, sets the address for the
various DWARF-related sections, causing this unusual code to be run.

This code came from an old commit:

However it was partially reverted here:

    https://sourceware.org/ml/binutils/2008-11/msg00134.html

This patch just completes the reversion.

Built and regtested on x86-64 Fedora 18.  I also ran the resulting
readelf against the Guile-created object with success.

I have no way of testing this on Mach-O, so your feedback is
solicited.

don't allocate serial_ops

Now that struct serial_ops is const everywhere, we can easily turn the
instances into globals.  This patch implements this idea.

On the one hand I think this is nicer since it makes a bit more data
readonly and slightly reduces allocations.  On the other hand it
reduces readability somewhat.

If the readability is a concern to anyone I was thinking I could write
a macro that conditionally uses GCC's designated initializer
extension.

mingw cross tools.

Fix PR breakpoints/16297: catch syscall with syscall 0

Code rationale
==============
by: Gabriel Krisman Bertazi

This is a fix for bug 16297. The problem occurs when the user attempts
to catch any syscall 0 (such as syscall read on Linux/x86_64). GDB was
not able to catch the syscall and was missing the breakpoint.

Now, breakpoint_hit_catch_syscall returns immediately when it finds the
correct syscall number, avoiding a following check for the end of the
search vector, that returns a no hit if the syscall number was zero.

Testcase rationale
==================
by: Sergio Durigan Junior

This testcase is a little difficult to write.  By doing a quick
inspection at the Linux source, one can see that, in many targets, the
syscall number 0 is restart_syscall, which is forbidden to be called
from userspace.  Therefore, on many targets, there's just no way to test
this safely.

My decision was to take the simpler route and just adds the "read"
syscall on the default test.  Its number on x86_64 is zero, which is
"good enough" since many people here do their tests on x86_64 anyway and
it is a popular architecture.

However, there was another little gotcha.  When using "read" passing 0
as the third parameter (i.e., asking it to read 0 bytes), current libc
implementations could choose not to effectively call the syscall.
Therefore, the best solution was to create a temporary pipe, write 1
byte into it, and then read this byte from it.

Extend SystemTap SDT probe argument parser

This patch extends the current generic parser for SystemTap SDT probe
arguments.  It can be almost considered a cleanup, but the main point of
it is actually to allow the generic parser to accept multiple prefixes
and suffixes for the its operands (i.e., integers, register names, and
register indirection).

I have chosen to implement this as a list of const strings, and declare
this list as "static" inside each target's method used to initialize
gdbarch.

This patch is actually a preparation for an upcoming patch for ARM,
which implements the support for multiple integer prefixes (as defined
by ARM's asm spec).  And AArch64 will also need this, for the same
reason.

This patch was regtested on all architectures that it touches (i.e.,
i386, x86_64, ARM, PPC/PPC64, s390x and IA-64).  No regressions were found.
