(1) Fix warnings. This is a bulk update to fix all the warnings that were causing build failures with -Werror on hppa. The most egregious problems are in dl-fptr.c which needs to be entirely rewritten, thus I've used -Wno-error for that. (2) Fix conformance errors. The sysdep.c file had __syscall_error and syscall in one file which caused conformance issues by including syscall when __syscall_error was linked to. The fix is obviously to split the file and use syscall.c to implement syscall.
