On Buildroot they don't pass -std=c99/g99 and this is the result:
https://gitlab.com/bootlin/toolchains-builder/-/jobs/1325646298
This patch seems to follow all the rest code style of binutils since no
other part of it fails and this happens only after patch [1] has been
upstreamed.
Here [2] you can see all the other toolchains built succesfully and only
Openrisc fails after the patch provided by Stafford([1]).
