          Hardware: PC

            Status: NEW
          Severity: enhancement

As of very recently, clang has stopped working in . It seems the binaries lack
the execution permission bit, leading to "make[2]: execvp: /usr/bin/clang++-7:
Permission denied".

The missing permission bit can be seen by inspecting the debian archive:

$ dpkg -c clang-7_7.0.1~svn348686-1~exp1~20181210143841.48_amd64.deb | grep
/usr/lib/llvm-7/bin/clang
-rw-r--r-- root/root  31056528 2018-12-10 14:38 ./usr/lib/llvm-7/bin/clang
lrwxrwxrwx root/root         0 2018-12-10 14:38 ./usr/lib/llvm-7/bin/clang++ ->
clang
lrwxrwxrwx root/root         0 2018-12-10 14:38 ./usr/lib/llvm-7/bin/clang-7 ->
clang
lrwxrwxrwx root/root         0 2018-12-10 14:38 ./usr/lib/llvm-7/bin/clang-cpp
-> clang
