[lmi-commits] [lmi] master 0bbe38b 2/3: Improve concinnity

[Greg Chicares]

branch: master
commit 0bbe38b2db1df162ac8393bd079dae09c76c6a2f
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Improve concinnity
    
    In each script that
     - is intended to be run at the command line, and
     - sources 'set_toolchain.sh', and
     - does not already cd to $srcdir,
    ascertain $srcdir and source '"$srcdir"/set_toolchain.sh'
    rather than assume that [ "$PWD" = "$srcdir" ] .
    
    Changed the only script that didn't already fulfill that invariant. See:
      https://lists.nongnu.org/archive/html/lmi/2020-10/msg00091.html
