* sysdeps/unix/sysv/linux/configure.in: New file, start with configure.
Add check for installed <linux/version.h> being v2.0 or later.
* sysdeps/generic/dl-sysdep.c (_dl_sysdep_open_zero_fill): Call __open
instead of open.
(_dl_sysdep_fatal): Call __write instead of write.
(_dl_sysdep_message): Likewise.

* sysdeps/m68k/fpu/e_acosl.c: New file.
* Makerules (o-objects): New variable. Use it in place of
$(objects:.o=$o); it filters out $(elide-routines$o).
Use o-iterator for ar and ranlib rules so they use the per-type object
list.
* sysdeps/unix/bsd/ultrix4/sys/mman.h: Likewise.
