I'm not sure I understand your question.  The LO build system requires 
Bash in places, esp. as the shell used to execute makefile recipe lines. 
  But that is unrelated to the fact that Autotools translates LO's 
configure.ac into a "#! /bin/sh" configure script, so that it should not 
use Bashisms.

(That said, it looks like OOO_SHELL is actually unused since we got rid 
of the old dmake-based build system, and could be dropped.  The use of 
Bash in gbuild is enforced via "SHELL=/usr/bin/env bash" in Makefile.mk, 
which should arguably be replaced with "SHELL=@BASH@".)
