32 bit cross compiling support on Linux Add the `m32` parameter to ./installdeps to fetch 32 bit multilib dependencies on Fedora, Arch and Solus linuxes and add a cmake toolchain file to build with them. For MSYS2 support both an `m32` and an `m64` to choose deps for 32 bit or 64 bit mingw targets. Adjust build instructions from ./installdeps to support both usages. Other changes: - use --nogpgcheck --best --allowerasing for dnf invocations for Fedora, the --nogpgcheck is necessary when Rawhide is confused about which keys it has, and the latter two are needed for upgrades that remove unneeded deps etc - when finding GTK2, first try using pkg-config, and only fall back to the cmake script when that fails, pkg-config works better for cross builds - add cairo to dep lists in ./installdeps for the time being - for arch, list individual packages from base-devel instead of base-devel that do not require gcc-libs because of potential conflicts between gcc and gcc-multilib
