[flashrom] [PATCH] Support Debian/kFreeBSD

[Carl-Daniel Hailfinger]

Apparently compilation worked before I introduced the target OS check
during compilation, but it seems the generated binaries back then might
have been incorrect for Debian/kFreeBSD.

This stuff should compile and run well. Output of
flashrom -V
on a desktop PC (not a laptop) would be appreciated.
