Bug#783241: fails to build cross compiler: "debian/tmp/usr/include/c++/5 not found"
Source: gcc-5
Version: 5.1~rc1-1
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap
Since the cxx_inc_dir removal in gcc-5, the full cross compiler build
fails:
| DH_COMPAT=2 dh_movefiles -plibstdc++-5-dev-arm64-cross usr/include/c++/5 usr/lib/gcc-cross/aarch64-linux-gnu/5/libstdc++.{a,so} usr/lib/gcc-cross/aarch64-linux-gnu/5/libsupc++.a

The path it tries to install looks suspiciously native and thus wrong.
And really the path gcc installed to was
"debian/tmp/usr/aarch64-linux-gnu/include/c++/5".
Looking at recent changes, you replaced $(cxx_inc_dir) with $(PF), but
formerly $(cxx_inc_dir) contained $(TARGET_ALIAS) for DEB_CROSS, which
is not covered anymore. Thus I suggest to replace two occurrences of
$(PF) with $(PFL) and have the build succeed.
