gperf not tested in config

the gperf command is not check by configure for step "Configure and make
LLVM-GCC" 

This resulted in a build failure with gpref command not found error, half
way through the build.

After installing gpref, from the current Fedora 7 repo.
$ gperf -v
GNU gperf 3.0.2
...
I got half way through $ make LLVM_VERSION_INFO=2.0-svn-iphone-dev-0.3-svn
where it failed with:

if the gperf error is not related to the last "make" error, maybe this
issue needs to be split.
