[cfe-commits] Use GCC_INSTALL_PREFIX to initialize SysRoot

But surely you won't be able to set DEFAULT_SYSROOT in the graphical/curses cmake cache editor (ccmake) because it isn't defined in CMakeLists.txt with help text etc.
It essentially makes it a hidden configure option.

This part seems to be working, but I found other problems. There are
more users of OPT__sysroot_EQ. You probably need to define a
getSysRoot function. You also should string the final / from both the
command line and configure option or from none.
I tried building with
cmake ../llvm/ -DDEFAULT_SYSROOT=/Developer/SDKs/MacOSX10.7.sdk/
and config.h has
#define DEFAULT_SYSROOT "/Developer/SDKs/MacOSX10.7.sdk/"
but that sysroot is not being prepended to the header search path for example.
