Fixes#3632
It's unclear why this option would be necessary, and it causes problems
when people do not match it to their toolchain and CFLAGS.
To set the float abi, either use a toolchain with an appropriate default
or set the float-abi option in the CFLAGS environment variable.
This should resolve#2586.
Recent cmake versions (starting with 3.0) don't use multiarch
libdir when the install prefix is not /usr. To have the same library
directory for all packages explicitly set CMAKE_INSTALL_LIBDIR to lib.
