[Debian-med-packaging] Bug#908353: ncbi-tools6 FTCBFS: uses the build architecture compiler

[Helmut Grohne]

Source: ncbi-tools6
Version: 6.1.20170106-4
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

ncbi-tools6 fails to cross build from source, because debian/rules
forces the build architecture compiler. Letting dpkg's buildtools.mk
initialize the CC variables fixes that part. Unfortunately, the cross
build still fails with a weired linker error:

| /usr/lib/gcc-cross/powerpc64le-linux-gnu/8/../../../../powerpc64le-linux-gnu/bin/ld: warning: libnetcli.so.6, needed by ../shlib/libncbiacc.so, not found (try using -rpath or -rpath-link)

I have no idea on how to fix that. Still, could you apply the attached
patch and close this bug when doing so? That'd make the real issue more
visible to others.
