On ia64-hpux version 11.31, <sys/ptrace.h> has been removed.
This patch adds a configure check for this header file, and only
includes <sys/ptrace.h> if it exists.
Rather than building the sources directly, create a library that
gets linked statically into libunwind.la and libunwind-$(arch).la.

Build DWARF source files into automake convenience libraries to
eliminate duplication in arch-dependent library build rules.
Adds a configure-time check to determine whether to use them.

The -static-libcxa test only applies for the Intel compiler, but the
check could pass for some versions of GCC. It would be accepted with
a warning in the past, but it produces an error with GCC 4.6.

Ensure that --enable-debug-frame is set automatically when building
libunwind for an ARM target. Other targets continue to have
--disable-debug-frame as the default setting.

Adds numerous AC_MSG_CHECKING and AC_MSG_RESULT pairings for
configuration tests that were previously unreported. Relocates
the debug configuration to the same part of the file as the command
line option declaration for associative clarity. Makes it easier
to confirm the resultant configuration matches original intentions.

Greetings,
Here is the second part, actually implementing the configure option.
Thanks,

New configure option to allow caller to block signals.
Provide a special implementation for ia64, because the unwind
information is such that an IP adjustment is not necessary before
looking up unwind info.
Bad things happen if libunwind only provides parts of the ABI and
the rest come from libgcc.

(pkg_minor): Switch to 99.
(pkg_extra): Switch to -alpha.
(CFLAGS): Add -fexceptions if we're compiling with GCC. It's
needed to get the proper unwind tables on platforms
with DWARF unwind info (well, at least on x86 it's needed).
(Logical change 1.290)
