[Debian-mobcom-maintainers] Bug#977516: osmo-bsc: build-depends on obsolete package.

[peter green]

Source: osmo-bsc
Version: 1.6.1+dfsg1-3
Severity: serious
Tags: ftbfs

osmo-bsc build-depends on libosmo-legacy-mgcp-dev, which has been dropped by the osmo-mgw
source package. It is still present in unstable as a cruft package, but is completely
gone from testing, meaning it is no longer possible to build osmo-bsc in testing.
