Suggested by David Barto https://lists.gnu.org/archive/html/help-bison/2015-02/msg00004.html and Victor Zverovich. https://lists.gnu.org/archive/html/bison-patches/2018-10/msg00121.html This is very easy to do, thanks to work by Bruno Haible in gnulib. See "Supporting Relocation" in gnulib's documentation. * bootstrap.conf: We need relocatable-prog and relocatable-script (for yacc). * src/yacc.in: New. * configure.ac, src/local.mk: Instantiate it. * src/main.c, src/output.c (main, pkgdatadir): Use relocatable2. * doc/bison.texi (FAQ): Document it.
