Subject: kbuild: Use uname for LINUX_COMPILE_HOST detection
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1e66d50ad3a1dbf0169b14d502be59a4b1213149;p=linux.git

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).
