dhrystone: fix compilation problems
This patch fixes two compilation errors with original
dhrystone sources:
* Redefinition of times() with wrong return type
- Fixed by commenting out the unnecessary redefinition
* Undefined identifier HZ
- Originally HZ was supposed to be the clock frequency
value for times()
- For Linux, the frequency should come from sysconf
- This patch defines global varible HZ and initializes
it from sysconf
Additionally, this patch adds a simple Makefile.
