PowerPC64 ld.so code. Mostly ported, code runs far enough to start first symbol string lookup.

Make sure the syscall table entries are aligned on a 4-byte boundary. Required for strict-alignment architectures and a good idea on others. same as kettenis commit to libc

crt0 uses a helper function in a MD src/libexec/ld.so .h file (rather than reproducing the relevant defines and code in a different place) to perform minor relocations. If things go very wrong, it would call _dl_exit() -- a locally defined crt0 function which is syscall exit(2). We don't need to call exit(2) for this obscure case which doesn't happen and provides no debugging information. An 'abort' is going to provide better information. So let's change the function name to _dso_abort() and make it a single illegal instruction. ok guenther

Populate the non-LOAD openbsd.syscalls section (and PT_OPENBSD_SYSCALL) with {uint offset, uint syscall#} entries in libc & ld.so. In libc a few syscall# entries (break, sigprocmask, _tfork, _threxit) are duplicated because additional or inline uses occur (that situation is handled elsewhere) ok kettenis

Prep .c files for removing the #includes from */archdep.h * replace #include "archdep.h" with #includes of what is used, pulling in "syscall.h", "util.h", and "archdep.h" as needed * delete #include <sys/syscall.h> from syscall.h * only pull in <sys/stat.h> to the three files that use _dl_fstat(), forward declare struct stat in syscall.h for the others * NBBY is for <sys/select.h> macros; just use '8' in dl_printf.c * <machine/vmparam.h> is only needed on i386; conditionalize it * stop using __LDPGSZ: use _MAX_PAGE_SHIFT (already used by malloc.c) where necessary * delete other bogus #includes, order legit per style: <sys/*> then <*/*>, then <*>, then "*"
