Source: llvm-toolchain-12
Version: 1:12.0.1-10
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)
The restructuring in 1:12.0.1-10 seems to have caused a build regression
on mipsel, which I'm reporting as separate from #996796 because it
doesn't affect i386:

[and lots more _Unwind_Foo references]
I assume this is resulting from -nodefaultlibs not causing libunwind
to be linked in where necessary?
Among non-release ports, powerpc also has this. mipsel and powerpc also
have #996796.

Source: llvm-toolchain-12
Version: 1:12.0.1-15
set LIBCXX_USE_COMPILER_RT to OFF in debian/rules to disable builtins when
libunwind is not enabled since the unwind implementation with gnu builtins
will then be required
