From 3edce6a0019bcb90febc1f654b5b2e2bad5c59bd Mon Sep 17 00:00:00 2001

Subject: [PATCH] fix compile failure with older host gcc (<=4.6)
While host gcc version is 4.6.3 in ubuntu 1204, it
did not recognize -std=gnu11 and -Wmaybe-uninitialized.
While host gcc version is 4.4.7 in centos6, it
did not recognize -std=gnu11, -Wmaybe-uninitialized,
and -flto.
For native build, use -std=gnu99 to replace -std=gnu11,
and directly remove -Wmaybe-uninitialized and -flto.
Upstream-Status: Pending
