I think you're confused with GDB's release numbering.
The set of 7.x releases are not all part of a single maintenance "gdb 7"
tree/family. Likewise, set of 8.x releases are not all part of a
single maintenance "gdb 8" tree/family.  I.e., 7.12 is not a maintenance
release of 7.11.  7.11 is not a maintenance release of 7.10.  etc.

GDB 7.12 was just as much of an increase over 7.11, as 8.0 was over 7.12.
It just happened that when we got all the way up to "12" we though that
that would be a good time to roll over to 8.0, because small numbers are
nice.

Maintenance bugfix releases are instead the z in x.y.z, as in
7.11.1, 7.11.2, etc.

Currently, we're about to release gdb 8.2, so the 8.2.x branch
in git is open for regression bugfixes.  Build fixes like yours
would be a good fit too.  It's possible to merge fixes to older
branches, but it's not very usual.  As we move on to newer
releases, the older branches tend to become unmaintained.
