[Buildroot] [git commit branch/2020.05.x] package/bison: disable libtextstyle

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=1172a76773da402e73674d74a28fc6efdd0a5e7a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.05.x

Recent bison versions added support for fancy error output using gettext
provided libtextstyle. The Buildroot gettext version does not provided
all needed features. However host-bison might detect host installed
libtextstyle at configure time, but fail at run time because of missing
symbols in Buildroot provided libtextstyle.

We don't really need fancy output of host packages, so just disable
libtextstyle support.

Fixes (libpcap):
