Strip generator's path info out of generated ini-parser file
Be honest, we're just not going to support 32bit.

The JIT specifically emits 64-bit x86 and will do so for

Rename CMake LibUODBC module.

Some spring cleaning for the cmake file

Don't even check USE_HHVM/USE_HPHPC, hphpc died months ago.
HHVM_BINARY and HHVM_LIB_PATH_DEFAULT defines are no longer used.
HHVM_PATH is specific to test.
Remove the need to export HPHP_HOME when building

"Detect" HPHP_HOME as the location of the main CMakeLists.txt
file and plumb it through to child scripts from there.
