The patch is OK, I'm just curious why we don't move flashbuses_to_text() into flashrom.c so the print can work consistently.

PS6, Line 9: o flashbuses_to_text() is a cli function and should actually be moved
           :   or not be called from flashrom.c.
Why not move flashbuses_to_text() to flashrom.c?

Hmm, I wonder if it's still useful to have a check for glibc compatibility while we're at it. According to the man page:
Since glibc 2.10:
    _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
    _GNU_SOURCE
