Hi
With this patch profiling works again on the ia64.
Jes

* NEWS: Update compile instructions for Linux/ia64.
* sysdeps/ia64/_mcount.S: Call __mcount instead of
__mcount_internal.
* sysdeps/ia64/Makefile: Compile _mcount.S in subdir gmon as
_mcount is required by profiled binaries.
* sysdeps/unix/sysv/linux/ia64/machine-gmon.h: Moved to...
* sysdeps/ia64/machine-gmon.h
