kbuild: Use uname for LINUX_COMPILE_HOST detection
`hostname` may not be present on some systems as it's not mandated by POSIX/SUSv4. This isn't just a theoretical problem: on Arch Linux, `hostname` is provided by `inetutils`, which isn't part of the base distribution. ./scripts/mkcompile_h: line 38: hostname: command not found Use `uname -n` instead, which is more likely to be available (and mandated by standards).
