[coreutils] [PATCH] tests: avoid portability problem with dash vs. local v=$splittable_val

[Jim Meyering]

Hi Pádraig,

When running make check SHELL=dash, I got one failure.
It was in misc/stat-birthtime, due to its use retry_delay_:

  + num_sleeps=16
  + test 5 -le 5
  + gawk -v n=16 -v s=.07 BEGIN { for (i=0;i<n;i++) t = s" "t; print t }
  + local delay=.07 .07 .07 .07 .07 .07 .07 .07 .07 .07 .07 .07 .07 .07 .07 .07
  local: 1: .07: bad variable name

Subject: [PATCH] tests: avoid portability problem with dash vs. local 
v=$splittable_val

* tests/init.cfg (retry_delay_): Put "local var" in a statement before
"var=...", to avoid portability problems with dash, when the RHS value
contains white space.
