[flashrom] [PATCH] Allow to compile out serprog completely

[Carl-Daniel Hailfinger]

Allow to compile out serprog completely. If CONFIG_SERPROG is not set,
no stubs and no data of serprog will remain.

Side benefit: This kills a few dozen lines of code.

r678, r679 and r680 made this possible.
Once "Only list available programers in usage()" is committed, even the
usage message will be adjusted automatically.
