[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=cefdd6546010e160985de2daa2ef70a952d081f6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Now that the build of efivar with gcc 7.x has been fixed by commit
0ca30170345a81f5f21e4ef4424b1f186cde1988 ("efivar: fix build with gcc
7"), efibootmgr fails similarly with gcc 7.x.

This commit backports an upstream patch that fixes this issue.
