Introduce get_rt_sigframe_addr function Add get_rt_sigframe_addr function for all supported architectures. It is going to be used in a parser of rt_sigreturn syscall. * defs.h (get_rt_sigframe_addr): New function prototype. * rt_sigframe.c: New file. * Makefile.am (strace_SOURCES): Add it. * linux/aarch64/arch_rt_sigframe.c: New file. * linux/alpha/arch_rt_sigframe.c: Likewise. * linux/arc/arch_rt_sigframe.c: Likewise. * linux/arm/arch_rt_sigframe.c: Likewise. * linux/avr32/arch_rt_sigframe.c: Likewise. * linux/bfin/arch_rt_sigframe.c: Likewise. * linux/crisv10/arch_rt_sigframe.c: Likewise. * linux/crisv32/arch_rt_sigframe.c: Likewise. * linux/hppa/arch_rt_sigframe.c: Likewise. * linux/i386/arch_rt_sigframe.c: Likewise. * linux/ia64/arch_rt_sigframe.c: Likewise. * linux/m68k/arch_rt_sigframe.c: Likewise. * linux/metag/arch_rt_sigframe.c: Likewise. * linux/microblaze/arch_rt_sigframe.c: Likewise. * linux/mips/arch_rt_sigframe.c: Likewise. * linux/nios2/arch_rt_sigframe.c: Likewise. * linux/or1k/arch_rt_sigframe.c: Likewise. * linux/powerpc/arch_rt_sigframe.c: Likewise. * linux/powerpc64/arch_rt_sigframe.c: Likewise. * linux/riscv/arch_rt_sigframe.c: Likewise. * linux/s390/arch_rt_sigframe.c: Likewise. * linux/s390x/arch_rt_sigframe.c: Likewise. * linux/sh/arch_rt_sigframe.c: Likewise. * linux/sh64/arch_rt_sigframe.c: Likewise. * linux/sparc/arch_rt_sigframe.c: Likewise. * linux/sparc64/arch_rt_sigframe.c: Likewise. * linux/tile/arch_rt_sigframe.c: Likewise. * linux/x32/arch_rt_sigframe.c: Likewise. * linux/x86_64/arch_rt_sigframe.c: Likewise. * linux/xtensa/arch_rt_sigframe.c: Likewise. * Makefile.am (EXTRA_DIST): Add them.
