ef042d8e23 add a linux_rt_sigframe to support SA_SIGINFO, and use it when SA_SIGINFO 
is requested. This appears to be how linuxthreads decides which signal handler
to use.

e1e0ff678b move ELF-specific items from irix_exec.c to irix_exec_elf32.c 
merge the two emul_irix structures; the only difference was
  setregs function, which can be handled by exec-specific setregs hook
rename setregs_n32() to irix_n32_setregs(), and make it suitable
  as the exec-specific setregs hook
make irix_check_exec() a macro now that just single compare

c9710a72e0 Get the dynamic interpreter location using emul_find_interp(), so that 
it checks both the alternative/emul tree, and the non-emul tree.
This makes it possible to run chrooted emulated binaries without need
to setup shadow /emul tree within the chroot hierarchy.

XXX sligh code rearrangement was necessary, change not tested

1bf46cc0f0 use emul_find_interp(), rathern than calling emul_find() second time 
with prefix set to "/"

47cd9b85d6 Get the dynamic interpreter location using emul_find_interp(), so that 
it checks both the alternative/emul tree, and the non-emul tree.
This makes it possible to run chrooted emulated binaries without need
to setup shadow /emul tree within the chroot hierarchy.
Only tested for COMPAT_LINUX, changes to other compat modules were
mechanical.

302af6f02e add emul_find_interp() function: the function looks for interpreter 
in alternative emul tree first, and updates interpreter pathname
if found there; if not found in alternative emul tree, pathname
without the emul prefix is checked, and error returned if the file
doesn't exist

dfa96ff4b3 Add signal delivery for the PowerPC. Everything is implemented except siginfo. 
The stack layout is observed from stack dumps on Darwin, so it should be
very accurate.

af59b63bbd We now have the exact stack initial stack layout of Darwin: 
macho_hdr, argc, *argv, NULL, *envp, NULL, progname, NULL,
*progname, **argv, **envp

Where progname is a pointer to the program name as given in the first
argument to execve(), and macho_hdr a pointer to the Mach-O header at
the beginning of the executable file.

1af0fa979f Better immitate Darwin startup stack layout: there is a slot for the program
