So I've been very interested in this problem (really don't know why kkkk)
but it may have a solution. This bug #725484 is similar to your problem.
Also in the last release 0.12 this a debian/NEWS was created, take a look:

blhc (0.12-1) unstable; urgency=medium

    Since 0.12 version, blhc is able to ignore false positives spotted by
    line(s) "injected" inside .build file via debian/rules. It is useful
    for Salsa automated tests and to skip wrong lines shown in local blhc
    report. See more details in blhc(1) manpage. There are examples in
    /usr/share/doc/blhc/README.Debian.

This might solve the problem. If it does, let us know.
