dump1090 build optimisations for debian

[nimbius]

during dump1090 builds, optimization warnings are thrown. can these be implemented?

dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/dump1090-fa/usr/bin/dump1090-fa debian/dump1090-fa/usr/bin/view1090-fa were not linked against libtinfo.so.5 (they use none of the library's symbols) dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/dump1090-fa/usr/bin/dump1090-fa debian/dump1090-fa/usr/bin/view1090-fa were not linked against ld-linux-armhf.so.3 (they use none of the library's symbols)

[mutability]

These are false positives.

specifically:

• ld-linux is the dynamic linker, you can't remove that
• libtinfo is a transitive dependency of libncurses
