Subject: build: Allow building from tarballs without yacc/lex
X-Git-Tag: v0.9.5~48
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2885cf2e65042b3dbc44fc232fd35840df255935;p=thirdparty%2Fnftables.git

build: Allow building from tarballs without yacc/lex

The generated files are included in the tarballs already, but
configure.ac was coded to fail if yacc/lex were not found regardless.
