Subject: omx: fix build with gcc 10
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=283e815339a15fa99039c69f1e225269790ae955;p=mesa.git

omx: fix build with gcc 10

bellagio/omx header files reference a global variable without the
extern keyworkd.
Now that gcc-10 enables the '-fno-common' by default the build fails.
Since these are external headers we can't easily fix them, so for
now build the omx module with the '-fcommon' flag to keep the
previous behavior.
