BUILDING.md: Specify install prefix for MinGW/Un*x The default install prefix when building under MinGW is chosen based on the needs of the official build system, which uses MSYS2 to generate Windows installer packages that install under c:\libjpeg-turbo-gcc[64]. However, attempting to configure the build with that install prefix on a Un*x machine causes a CMake error. Fixes #641
