Subject: configure.ac: use a single require_libdrm helper
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9898c60745504ade362711c4d6d0466f45268367;p=mesa.git

configure.ac: use a single require_libdrm helper

Rather than having 4-5 places which do the explicit check/message just
polish the gallium helper and use it everywhere.
