Bug#1010629: libc++-14-dev: provide memorysanitizer enabled variants of libc++ and libc++-abi

[Norbert Lange]

Package: libc++-14-dev
Version: 1:14.0.0-2
Severity: wishlist
X-Debbugs-Cc: nolange79 at gmail.com

Dear Maintainer,

the MemorySanitizer basically requires all used libraries (outside of libc)
to be recompiled.
Given that a C++ library is needed for any C++ Application, providing
libc++ and libc++-abi would be very welcome.

Unfortunatly the llvm-toolchain package is rather complex, so it
is too much for me to figure out a solution.

The idea is that a separate package would install the instrumented
libraries into a subdirectory like
/usr/lib/x86_64-linux-gnu/msan/libc++{.so,.a}
/usr/lib/x86_64-linux-gnu/msan/libc++abi{.so,.a}
