[flashrom-gerrit] Change in flashrom[master]: Makefile: Explicitly set '-std=c99'

[Edward O'Callaghan (Code Review)]

Hello Sam McNally, build bot (Jenkins), Nico Huber, Angel Pons,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/flashrom/+/47908

to look at the new patch set (#3).

Change subject: Makefile: Explicitly set '-std=c99'
......................................................................

Makefile: Explicitly set '-std=c99'

This matches the build flags that are correctly explicitly defined in
meson.build where-as the Makefile is randomly picking up whatever the
system toolchain happens to default to.

Fix dmi.c while we are here to avoid a re-define of _GNU_SOURCE.

BUG=none
TEST=`make` with both gcc and clang.
