Hi Matthias,
trying to build gcc-7 with DEB_STAGE=rtlibs results in an error over
here. A nios2 build[1] fails with:

When DEB_STAGE=rtlibs, debian/rules.defs sets the TS variable to an
empty string. This is propagated to m4 and thus the base package in
debian/control ends up without a target suffix. I think this is correct,
because rtlibs mostly tries to mimic a reduced cross build (not cross
compiler build). However, the make variable p_base includes the target
suffix as DEB_CROSS is set to yes. The attached patch fixes the value of
p_base when DEB_STAGE is set to rtlibs. Please consider applying it.
