Compiling on ppc is not working proplery.

[GoogleCodeExporter]

Compiling on PPC is not working properly. Because the mmap syscall is not 
properly defined.

Here is a patch to fix it.

Wow, this code dates back to 2007!  Has nobody tried to use perftools on PPC 
before this?  Or maybe PPC64 works ok, but not PPC32.

In any case, I'll ask the original author of this code to review, and assuming 
it looks ok, get it into the next release.

I've made many changes to linux_syscall_support.h for this release, including 
this one.  So this should be fixed in perftools 1.10, just released.  However, 
I don't have a PPC box to test on, so who knows... let me know if you still 
have problems!
