[Mesa-dev] [PATCH 2/2] configure.ac: append to existing initializer override flags

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

Currently we were overwriting the existing warning flags, instead of
adding new [as applicable].

Fixes c5d2e2d43f6 ("configure: Test for -Wno-initializer-overrides")
