Not true on two counts:

1) Shipping GPL covered software is not incompatible with "commerce".  You
can sell it and charge money for it, you just have to give your customers
the same rights that you have.

2) The only part that causes a problem is the parser skeleton.  If you
ship object code, plus the body of the tables generated by bison, you can
have your customers attach the bison parser skeleton to the tables,
compile that one file, and link to your object code.  In fact, you can
prelink your (presumably numerous) object code files into one file, and
strip everything but the necessary unresolved references and relocation
information.  It does not cause a problem to ship the bison parser
skeleton if it is in its own file.

For that matter, you can write your own version of the bison parser
skeleton that uses the same tables.
