This expands the `cross` travis matrix entry with a few more targets that our nightlies are building: * x86_64-rumprun-netbsd * arm-unknown-linux-musleabi * arm-unknown-linux-musleabihf * armv7-unknown-linux-musleabihf * mips-unknown-linux-musl * mipsel-unknown-linux-musl This commit doesn't compile custom toolchains like our current cross-image does, but instead compiles musl manually and then compiles libunwind manually (like x86_64) for use for the ARM targets and just uses openwrt toolchains for the mips targets.
