BeOS-PPC: problem in libiberty

[Andreas Sesterhenn <Andreas dot Sesterhenn at cgtec dot sema dot de>]

Hi,

this is my first attempt to post a patch... I hope I did it correctly
(I folowed the instuctions from README-BUGS in the gcc directory)

The Problem:
1)
./configure on my BeBox66 (R3.2) detects the correct machine type
(BeOS-ppc)

2)
when make tries to compile getruntime.c in libiberty the compiler
complaines about
an undefined 'HZ'. in function 'get_runtime'
I checked otherplaces for 'HZ' and found in gcc/FSChangeLog that I
should prefer
CLK_TCK or _SC_CLK_TCK if available (which is on my BeBox).

What surprised me was that in gcc/toplev.c is anothe function
'get_runtime' which
in case of compiling for BeOS simply returns 0 (without any further
comment) instead 
of what is nicely calculated afterwards.

I decided to include the nicely calculated result into getruntime.c
which compiles
correcty (say without any problems, whatever that means when it has to
run later).

Here is the patch (at least my first attempt. Let me know if I can
improve anything):
