Description:
* This patch enables libbacktrace to handle XCOFF on AIX.
Tests:
* Fedora25/x86_64 + GCC v7.1.0 : Configure/Build: SUCCESS
- build made by means of a .spec file based on Fedora gcc-7.0.1-0.12 .spec file
../configure --enable-bootstrap --enable-languages=c,c++,objc,obj-c++,fortran,go,lto --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-shared --enable-threads=posix --enable-checking=release --enable-multilib --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-gcc-major-version-only --with-linker-hash-style=gnu --enable-plugin --enable-initfini-array --with-isl --enable-libmpx --enable-offload-targets=nvptx-none --without-cuda-driver --enable-gnu-indirect-function --with-tune=generic --with-arch_32=i686 --build=x86_64-redhat-linux
ChangeLog:
* libbacktrace/Makefile.am : Add xcoff.c
* libbacktrace/Makefile.in : Regenerated
* libbacktrace/configure.ac : Add XCOFF output file type
* libbacktrace/configure : Regenerated
* libbacktrace/fileline.c : Handle AIX procfs tree
* libbacktrace/filetype.awk : Add AIX XCOFF type detection
* libbacktrace/xcoff.c : New file for handling XCOFF format

this patch broke Solaris bootstrap:
/vol/gcc/src/hg/trunk/local/libbacktrace/fileline.c: In function 'fileline_initialize':
/vol/gcc/src/hg/trunk/local/libbacktrace/fileline.c:105:41: error: format '%d' expects argument of type 'int', but argument 4 has type 'pid_t {aka long int}' [-Werror=format=]
snprintf (buf, sizeof (buf), "/proc/%d/object/a.out", getpid ());
~^ ~~~~~~~~~
%ld
The following patch allowed bootstrap to finish.

Tony,
This patch seems like a reasonable start for the minimal libbacktrace
framework needed by GCC Go. The libbacktrace maintainer, Ian, needs
to approve the patch.
https://gcc.gnu.org/ml/gcc-patches/2017-05/msg01186.html
I'll defer to Ian on the style of the fileline.c changes.
Thanks, David
