Subject: guile: handle readline support explicitly
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f8ce3d329778f39f097d959ac631cfff7d05bf49;p=buildroot.git

guile: handle readline support explicitly

Otherwise the host readline (+ncurses) development files can poison the
build causing breakage. Fixes:
