Subject: [PATCH] init/Kconfig: Specify the interpreter for rust-version.sh
Some common tools like 'diff' don't support permissions of the files.
Due to that, 'rust-version.sh' in some trees including '-mm' result in
having no execution permission, and therefore build fails like below:
$ make O=../linux.out/ olddefconfig
make[1]: Entering directory 'linux.out'
GEN Makefile
sh: 1: linux/scripts/rust-version.sh: Permission denied
init/Kconfig:71: syntax error
init/Kconfig:70: invalid statement
linux/scripts/kconfig/Makefile:77: recipe for target 'olddefconfig' failed
make[2]: *** [olddefconfig] Error 1
linux/Makefile:666: recipe for target 'olddefconfig' failed
make[1]: *** [olddefconfig] Error 2
make[1]: Leaving directory 'linux.out'
Makefile:226: recipe for target '__sub-make' failed
make: *** [__sub-make] Error 2
It's not a big deal, but not so fun. This commit fixes the issue by
specifying the interpreter for 'rust-version.sh' in the Kconfig file.
