kbuild: Add a space after `!` to prevent parsing as file pattern Some shells use !(pattern|...|pattern) to match file names not containing the specified patterns. This may result in output like $ ./scripts/clang-version.sh gcc ./scripts/clang-version.sh[18]: COPYING: not found printf: %d __clang_major__: conversion error printf: %d __clang_minor__: conversion error printf: %d __clang_patchlevel__: conversion error 00000 $ and set CONFIG_CLANG_VERSION to the invalid value '00000'. POSIX says[0] If the pipeline begins with the reserved word ! and command1 is a subshell command, the application shall ensure that the ( operator at the beginning of command1 is separated from the ! by one or more <blank> characters. The behavior of the reserved word ! immediately followed by the ( operator is unspecified. So, just add a <blank> to prevent this.
