    kbuild: Make the setlocalversion script POSIX-compliant · 6dc0c2f3
    Michał Górny authored
    The 'source' builtin is a bash alias to the '.' (dot) builtin. While the
    former is supported only by bash, the latter is specified in POSIX and
    works fine with all POSIX-compliant shells I am aware of.
    
    The '$_' special parameter is specific to bash. It is partially
    supported in dash too but it always evaluates to the current script path
    (which causes the script to enter a loop recursively re-executing
    itself). This is why I have replaced the two occurences of '$_' with the
    explicit parameter.
    
    The 'local' builtin is another example of bash-specific code. Although
    it is supported by all POSIX-compliant shells I am aware of, it is not
    part of POSIX specification and thus the code should not rely on it
    assigning a specific value to the local variable. Moreover, the 'posh'
    shell has a limited version of 'local' builtin not supporting direct
    variable assignments. Thus, I have broken one of the 'local'
    declarations down into a (non-POSIX) 'local' declaration and a plain
    (POSIX-compliant) variable assignment.
