1998-08-21 Roland McGrath <roland@baalperazim.frob.com>
* elf/ldd.bash.in (TEXTDOMAIN, TEXTDOMAINDIR): Surround setting these with magic comments ###BASH-ONLY and ###END-BASH-ONLY. * elf/Makefile ($(objpfx)ldd): Generate always from ldd.bash.in. (common-ldd-rewrite): New variable, old contents of $(sh-ldd-rewrite). (sh-ldd-rewrite): Use that, add cmds to remove code surrounded by those magic comments, and to use /bin/sh for @BASH@. (bash-ldd-rewrite): Use $(common-ldd-rewrite). * elf/ldd.sh.in: File removed.
