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.

** New features
*** Bison is now relocatable
If you pass '--enable-relocatable' to 'configure', Bison is relocatable.
A relocatable program can be moved or copied to a different location on
the file system. It can also be used through mount points for network
sharing. It is possible to make symlinks to the installed and moved
programs, and invoke them through the symlink.
*** %expect and %expect-rr modifiers on individual rules
One can now document (and check) which rules participate in shift/reduce
