debug/strace: pump version to 4.7 and 4.8

Pump version for strace to 4.7 and 4.8.
Add patch from strace mainline.


Work around conflict between <sys/ptrace.h> and <linux/ptrace.h>

Since glibc-2.18~39 <sys/ptrace.h> defines ptrace_peeksiginfo_args
which collides with <linux/ptrace.h>.

* configure.ac: Check for `struct ptrace_peeksiginfo_args' in
<sys/ptrace.h>.
* process.c: Work around potential conflict between <sys/ptrace.h>
and <linux/ptrace.h> by redefining ptrace_peeksiginfo_args.
* signal.c: Likewise.
* syscall.c: Likewise.
* util.c: Likewise.

     3 I tried to use crosstool-ng to generate a toolchain for Linux on big

     4 endian arm with recent versions of gcc, glibc, etc... but had a few

     5 problems.

     6 

     7 It appears that the gcc patch (for gcc 4.2.x)

     8 for big-endian arm (240-arm-bigendian.patch) lacks the change attached

     9 to this mail as 240-arm-bigendian2.patch.
