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
