Subject: configure: Test for -Wno-initializer-overrides
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c5d2e2d43f697d4d9d35542f3839fcacaf848885;p=mesa.git

configure: Test for -Wno-initializer-overrides

Clang has "-Wno-initializer-overrides", while gcc has
"-Wno-override-init". Quiets a lot of warnings with clang.
